Impact of multiple slips on thermally radiative peristaltic transport of Sisko nano ﬂ uid with double di ﬀ usion convection, viscous dissipation, and induced magnetic ﬁ eld

: The analysis focuses on investigating the phenomenon of double-di ﬀ usive convection using the Sisko nano ﬂ uid model. It particularly highlights the impact of induced magnetic ﬂ ux, viscous dissipation, and heat radiation within an asymmetric geometry having multiple slip conditions. To ascertain the salient of the Brownian di ﬀ u-sion coe ﬃ cient and thermophoresis, we have incorporated viscous dissipation, heat radiation, and the Buongiorno model. The Soret and Dufour parameters describe the convective double di ﬀ usion phenomenon. The mathematical formulation is constructed through equations governing magnetic force function, concentration, temperature, momentum, and continuity. These formulations yield nonlinear partial di ﬀ eren-tial equations to explain the designated ﬂ ow. To simplify the nonlinear partial di ﬀ erential equations, the lubrication paradigm of mathematical simulations is employed. The subsequent system of coupled nonlinear di ﬀ erential equations is calculated numerically through the NDSolve function, which is a built-in program of Mathematica. Numerical results and graphs give evidence that supports the signi ﬁ cance of di ﬀ erent ﬂ ow quantities in physiological contexts. The ﬁ ndings from this investigation are anticipated to contribute to the development of intelligent magneto-peristaltic pumps, particularly in thermal and drug administration applications. The current investigation suggests that the distribution of temperature reduces as the coe ﬃ cient of radiation increases due to a system ’ s high heat emission and consequent e ﬀ ects of cooling. Furthermore, the increased in ﬂ uence of heat radiation raises the concentration pro ﬁ le. It is also highlighted that heat radiation has the potential to raise a ﬂ uid ’ s temperature, which raises the volume fraction of nanoparticles.

One of the significant physiological phenomena is peristaltic flow which has wide-ranging utilization in engineering fields and biomedicine, specifically in scenarios having micro/macro level transportation.These flows involve diverse functions both in human physiology and industrial applications that encompass transportation and excretion of body fluids as well as handling of corrosive liquids and various machine applications like roller and finger pumps.These diversified practical applications of peristaltic flow have instigated researchers to further explore the phenomenon.In 1960, Latham [1] explained this phenomenon in detail in his MS research where he explained the process as "natural siphon" which employs rhythmic squeezing that travels along the chamber walls and pushes the contents within the chamber or vessel.Jaffrin and Shapiro [2] conducted a detailed analysis of the process.Later, researchers like Misra and Rao [3], Hina et al. [4], Akbar et al. [5], Safia Akram et al. [6], and Nadeem et al. [7][8][9][10] experimented with the process having different fluids under various conditions involving numerous parameters both physiological and mechanical.Despite these investigations, there are diverse limitations and unresolved issues which necessitate further indepth analysis and exploration.
Another influential area of peristaltic flow is nanofluids which have significant applications in medical engineering and biomedicine.The composition of nanofluid contains tiny oxides of metals, carbon nanotubes, and other carbon ions.However, the quantity of nanoparticles is minimal, which is calculated as less than 5%.Incredibly, a negligible amount like 1% added in the base fluid of nanostructure like fibre, sheet, rod, or wire could augment the heat properties by a considerable increase in heat conductivity.So, the addition of a minimal amount of nanoparticles can significantly enhance thermal flow.Choi and Eastman [11] explained the dispersion of nanosized particles within a heat-transmitting fluid.Similarly, Masuda et al. [12] further explored the nanofluid properties in terms of heat expansion and conductivity.A model is devised by Duangthongsuk and Wongwises [13] to examine nanofluid's thermophysical characteristics and its impact on the liquid's convection heat flow constant at the lowest nanoparticle concentration.Buongiorno and Hu [14] and Buongiorno [15] have investigated the Brownian diffusion with thermophoresis to understand the convective flow in nanofluids by applying a closed-form model.Another development to explain the dispersion of concentration polarity within the range of micro to nanochannel is through various models of analysis that is done by Mani et al. [16].Whereas Akbar and Nadeem [17] combined the concept of nanofluids with models of peristaltic pumping to examine the nanofluid peristaltic flow under the endoscopic influence.Moreover, Akbar [18] observed the Sisko nanoliquid peristaltic flow in an asymmetric channel.Particularly, the examination reveals that an increase in parameter axial pressure of Sisko nanoliquid leads to a rise in the area of peristaltic pumping.The research literature contains a wide range of studies [19][20][21][22][23][24][25] which further shed light on the phenomena of non-Newtonian and Newtonian nanofluids under various parameters and different flow structures.Moreover, the concept of magnetohydrodynamics is salient in sweltering heat equipment like electric transformers, as well as in corporal conductive matter including pumps and machines for blood regulation and arterial blood flow, Magnetic resonance imaging, equipment for magnetic therapies, and in aviation where inclined magnetic flux impact is noticeable.In biomedicine and medical engineering issues, [26][27][28][29][30] peristaltic flow with magnetic flux has provided multifaceted solutions.In electrically charged fluids having optimal Reynolds number, magnetic diffusion is negligible as compared to induction, hence resulting in the significant impact of induced magnetic flux.Taking into consideration the velocity slip conditions, Shit et al. [31] observed the micropolar fluid peristalsis under magnetic flux.The results reveal the strengthening of peristalsis flow under magnetic influence causing mechanical simulation of the fluid.Therefore, induced magnetic force is effective for the treatment of cancers and magneto therapy is recommended in research [32][33][34].Other notable findings are given in previous studies [29,[35][36][37][38][39].
The study of hydromagnetic peristaltic flow under thermal production and consumption impact has significant importance in various engineering and scientific fields.These encompass multifarious applications like processing of energy, and cooling and heating systems employed in industrial processing and in space technology and devices.Additional research exploring the phenomenon of peristalsis with heat and nanofluids is referred in previous studies [40][41][42][43][44].These investigations further delved into the various parameters including Brownian conditions, Hartmann number, and thermophoresis.Double diffusion is a phenomenon of typology of convection with two asymmetric density gradients called solutal and density gradients, respectively.It exhibits differing diffusion rates.Numerous natural, technical, and industrial scenarios use blended convection motion that integrates the force and free convection flows.Any fluid having two contrasting density gradients at differing rate of diffusion leads to free mixed convection with double diffusion [45,46].The practical utilization of hydromagnetic flow with heat dissemination properties includes wide industrial applications in nuclear reactor processes, manufacturing of electronic equipment and devices, which are few to mention.Owing to its extensive scope, the phenomenon has been investigated with various models of peristalsis and nanofluids flow [47][48][49][50][51][52][53].
Furthermore, the conventional use of no-slip situation is inefficient in case of fluids having wall slip condition with macroscopic context as it involves the relation of grip and slip velocity.The role of slip condition is salient in different procedures such as hysteresis impacts, spurt, and shear skin.Similarly, nanofluids with boundary slip conditions are used in technology to build devices like artificial heart valves and conduits.Further notable studies are referred in previous studies [54][55][56][57][58][59].
Due to the vast applications of the phenomenon mentioned above, the present study employs a unique merging of various intricate factors like heat radiation, induced magnetic flux, peristaltic transportation, viscous dissolution, multiple slip conditions, nanofluid, and double diffusive convection.The aim of the current investigation is to analyse the flow behaviour employing advanced mathematical and computational techniques.The study focuses on the fluid transportation with 2D peristalsis in an asymmetric channel.The driving force of the flow is sinusoidal waves transmitted through walls of the chamber with specific wavelength and persistent speed.The equation of temperature, mass, magnetic flux, concentration, momentum, and nanoparticle fraction is employed on fluid peristaltic transportation across the channel walls under slip boundary conditions.For the study, Mathematica command, NDSolve is employed for numerical solutions along with non-dimensional procedure.The result's findings are represented in graphical representations of concentration, velocity, nanoparticle fraction, magnetic force function, and temperature that not only provides ease in the analysis but also depicts parameters variation and its impact on system's behaviour.A comprehensive analysis of the results findings is presented in Section 4, while the significant resultant factors are summed up in the conclusion.It is noteworthy that insight of the convective double diffusion phenomenon upon nanoparticles in peristalsis have significance to assist in boosting nanofluid devices, enhance devices using microfluids, efficacious drug delivery, and proficient heat transmission systems.

Mathematical model
To investigate the peristaltic flow of Sisko nanofluid under dense and electrically charged medium, we consider the analysis of a two-dimensional channel, characterized by width The channel promotes sinusoidal waves at uniform velocity along the channel walls, serving as the source of initial flow.To facilitate the study, a coordinates system is adopted where the centre of the channel is aligned with X -axis, while the cross section of the channel lies along the Y -axis.The geometry of the problem under consideration is given in Figure 1.
The mathematical depiction of the wall's geometric forms is described as follows: Impact of multiple slips on thermally radiative Sisko nanofluid  3 where ( ) In this analysis, the right ( = y W 1 ) and left ( = y W 2 ) walls are retained at temperature (T 0 , T 1 ), concentration of the solvent at (C 0 , C 1 ), and nanoparticles volume fraction ) ) is used to represent the flow as two-dimensional and directional.Additionally, we introduced an outer transverse magnetic flux at uniform rate Z 0 , an induced magnetic force ) ) and accumulative magnetic flux ) ) for the analysis.The basic equations for hydro-magnetic Sisko nanofluid are as follows: (a) Maxwell's equation [31][32][33] is given as where V , E, μ , e J , and σ refer to the velocity vector, induced electric field, magnetic permeability, current density, and electric conductivity.

(b) Equation of continuity is given as
(c) Momentum equation is defined as [47,48,50] where T indicates the temperature, where P stands for the pressure and I is the Identity tensor.
(d) The nanoparticle thermal energy equation in the presence of mixed convection, radioactive heat flux, and viscous dissipation is defined as [49,52] where ρc f ( ) refers to the fluid's heat capacity, k stands for the thermal conductivity, ρc p ( ) represents the heat capa- city of effective nanoparticles, D B is the component of Brownian diffusion, D T refers to the coefficient of thermo- phoretic diffusion, D TC stands for the Dufour diffusivity, L stands for the velocity gradient, ∇ 2 stands for the Laplacian operator, and q r stands for the radiation thermal flux, which can be established by using the Rosseland diffusion technique as: Figure 1: Geometry of the problem.
The tremendous radiation limit is considered in this investigation.Therefore, by assuming that there are not any substantial temperature changes inside the flow channel, Taylor expansion may be used to modify T 4 such that temperature can be expressed as a linear function.With respect to T 0 , Taylor expansion on T 4 is now defined as Now we obtain − T T 0 ( ) by omitting the higher powers of T (more than the first).
(e) The solute concentration is defined as [49,52] where D CT and D s indicate Soret diffusivity and solutal diffusivity, respectively.(f) The nanoparticle volume fraction is defined as [49,52] 2)-( 4) where = ξ μ σ e is magnetic diffusivity.Since we are interested in performing the flow simulation in wave frame (x y , ).Therefore, the Galilean transfor- mation relates the velocities and coordinates in the laboratory X Y , ( ) and wave x y , ( ) frames as where u v , ( ) and U V , )indicate the velocities in wave and laboratory frames, respectively.
The following quantities are defined in order to express the flow of fluid in a non-dimensional form as Using Eqs. ( 18) and ( 19), Eq. ( 5) is automatically satisfied and Eqs. ( 6)- (17) in terms of the stream function ψ and magnetic force function Φ (dropping the bars) are as follows: Impact of multiple slips on thermally radiative Sisko nanofluid  5 where  8), and is defined as follows: Now using ≪ δ 1 (long wavelength) and finite approx- imation of a low Reynolds number, Eqs. ( 20)- (26) become where Now pressure is eliminated from Eqs. ( 27) and ( 28) to yield the stream function equation as The boundary conditions in non-dimensional form are expressed as (37) where l , 1 l , 2 l , 3 and l 4 stands for velocity slip parameter, temperature slip parameter, concentration slip parameter, and nanoparticle slip parameter, respectively.The no slip conditions in the aforementioned criteria are indicated when l , 1 l , 2 l , where where 3 Special cases • The results of Akbar [18] can be recovered as a special case of our problem by dropping/ignoring the phenomena of induced magnetic field Φ , ( ) viscous dissipation (Br), slip parameters l l l l , , , ,   and excluding the phenomena of heat transfer, double diffusion convection, slip parameters, and induced magnetic field, the results of the viscous fluid [3] can be found as a special case of our problem (Table 1).

Numerical solution and graphical analysis
The exact solution to Eqs. ( 27), ( 29)- (32), and (34) appears to be difficult to attain; the solution may be found by using computing techniques.Mathematica 9 and MATLAB software is used for performing the numerical computations of Eqs. ( 27), ( 29)-( 32), and (34).NDSolve command is utilized for solving the nonlinear equations in Mathematica.NDSolve is basically a Wolfram Language that is used to solve numerical differential equations.It is capable of solving a large of ordinary differential equations and certain partial differential equations.In NDSolve, the solutions for the functions are represented by interpolating function objects.The interpolating function objects approximate the function throughout the independent variable's range of minimum to maximum values.In general, NDSolve iteratively discovers solutions.To investigate the thermodynamic features of our model, a graphical analysis of the numerical results is produced.The effects of pressure rise on non-Newtonian parameter (r), velocity slip (l 1 ), thermophoresis parameter (N t ), and thermal slip (l 2 ) are analysed in Figure 2(a)-(c).To expose all aspects of pressure rise, the pumping phases are classified into the following segments: a) The augmented exists when Q < 0 and Δp < 0: The pressure induced by the peristaltic force enhances flow in this area.b) The peristaltic region exists when Q > 0 and Δp > 0 gt is 0: Fluid is propelled in the direction of flow by peristalsis waves, which continually regulates the pressure in this area.c) The retrograde region exists when Q < 0 and Δp > 0: Peristalsis contractions are preventing the flow in this area, which increase pressure in the direction opposite to the flow.The retrograde motion may generate a "backflow" effect that spreads the fluid and avoids system congestion.d) The free pumping region exist when Δp = 0 and Q = 0: Peristalsis walls are the sole means of flow in this region.
It is seen from Figure 2(a) that increasing the influence of the non-Newtonian parameter (r) increases the pressure rise in the zones of retrograde, free, and peristaltic pumping, but the reverse effect is seen in the augmented region.Here pressure rise drops because of the rising influence of r.In Figure 2(b), it is shown that as the influence of velocity slip (l 1 ) increases, the pressure rise falls in the peristaltic, free, and retrograde pumping zones, but the opposite behaviour is noted in the augmented pumping region.The rising influence of velocity slip causes pressure to increase in this region.As observed in Figure 2(c) and (d), increasing the thermophoresis (N t ) and thermal slip (l 2 ) parameters cause pressure to increase in all peristaltic pumping zones.Figure 3(a)-(d) depicts the significance of various parameters on the pressure gradient distribution.It is noted from Figure 3(a) that increasing the non-Newtonian variable causes the pressure gradient to accelerate at the central region of the channel while decreasing towards the right and left sides.According to Figure 3(b), the pressure gradient reduces in the region x ∈ [0.3,0.6]due to the increasing impact of velocity slip, whereas it increases in the regions x ∈ [0,0.3] and x ∈ [0.6,1].As illustrated in Figure 3(c) and (d), the pressure gradient drops as a result of the increasing impact of nanoparticle Grashof number (G rF ) and thermal radiation (Rd).
The phenomenon of flow velocity is investigated in Figure 4(a)-(d) for various values of non-Newtonian parameter (r), velocity slip (l 1 ), thermophoresis (N t ), and thermal radiation (Rd).As depicted in Figure 4  Here magnitude value of fluid velocity decreases as l 1 increases.As shown in Figure 4(c), fluid velocity tends to rise when it is in the region x ∈ [−1.0,1.6],but it tends to drop when it is in the region x ∈ [−2.5, −1] due to an increase in the influence of thermophoresis (N t ) parameter.The fluid velocity exhibits opposite behaviour on thermal radiation (Rd) when compared to the thermophoresis (N t ) parameter.The velocity profile enhances when fluid is in the region x ∈ [−2.5, −1.3] and drops when the fluid is in the region x ∈ [ − 1.3,1.6]due to the enhancing influence of thermal radiation (Figure 4(d)).
Figure 5(a)-(d) displays the effect of temperature distribution on Brinkman number (Br), thermal slip parameter (l 2 ), radiation parameter (Rd), and Brownian motion (N b ). Figure 5(a) illustrates the impact of Brinkman number (Br) on temperature distribution.It is demonstrated in this figure that by using Br, it is possible to increase the internal resistance among the fluid's particles, which leads to a better temperature distribution.A similar characteristic is being investigated in Figure 5(b) for the thermal slip parameter (l 2 ). Figure 5(c) shows the graphical impact of temperature on radiation (Rd) parameter.This figure illustrates that increasing the values of the radiation parameter reduces temperature.It is due to the fact that as the radiation parameter rises, heat conduction is reduced, and electromagnetic wave motion is improved.Because irregular atom growth leads to dispersion of heat exchange, when it is sent out, the adjoining particles spread less and the vitality exchange rate between them slows down.Diffusive heat exchange also happens more slowly than radiative heat exchange.It is noted in Figure 5(d) that the system's temperature may change as a result of the Impact of multiple slips on thermally radiative Sisko nanofluid  11 enhanced Brownian motion.This occurs because when particles collide more frequently and violently, some of their kinetic energy is transferred to the suspended particles.The particles internal energy is increased, and their temperature is raised as a result of the energy transfer.Therefore, a rise in Brownian motion usually correlates with a rise in temperature.
Figure 6(a)-(d) displays the characteristics of solutal concentration on slip parameter of concentration (l 3 ), Soret parameter (N CT ), Prandtl number (Pr), and radiation parameter (Rd).Figure 6(a) demonstrates that the concentration profile decreases as a result of the increasing influence of the concentration's slip parameter (l 3 ).It is noted in Figure 6(b) that due to the increasing impact of the Soret parameter, the profile of concentration tends to drop.The Soret parameter shows a higher impact of heat diffusion on concentration profiles as it rises.In these situations, the concentration profile frequently exhibits a tendency to decline or become more reduced in areas of greater temperature.As seen in Figure 6(c), a rise in the Prandtl number causes irregularities and a general drop in the particle distribution.The flow field's temperature rise is the primary factor in the lowering of nanoparticle concentration, which is caused by the temperature of the channel.The radiation parameter exhibits opposite effect on concentration profile when compared to l 3 , N CT , and Pr.The concentration profile rises due to the increasing influence of heat radiation.Increased movement of molecules and energy transfer throughout the system might be a result of high radiation intensity.This improved molecular mobility may cause diffusion coefficients to rise, facilitating the transport of particles throughout the medium.The

Streamlines
The conceptual lines, used in fluid dynamics, are called streamlines.These hypothetical lines depict the instantaneous direction of fluid movement at varying points within the fluid field.When taken into consideration in the study of peristaltic flow, the streamlines have significance as they provide valuable insights through flow patterns and pathways of fluid particles in the system.Hence, the streamlines analysis is beneficial for the development and enhancement of peristaltic flow system.The visualization of streamlines enables the researchers to detect zones of flow separation areas, characterized by elevated sheer stress, or potential sites for particle deposition.This   knowledge is invaluable as it can be used to develop more efficient peristaltic devices or improve the parameters matrix for specified flow characteristics.
The impact of streamlines on velocity slip l 1 ( ), thermal slip l 2 ( ), concentration slip l 3 ( ), and nanoparticle slip l 4 ( ) parameters are examined in Figures 9-12.According Figure 9, the quantity and shape of the trapped bolus reduces in both the top and bottom regions of the channel as the velocity slip increases.This occurs because velocity slip may strengthen the fluid mixing, especially at channel boundaries.This improved mixing may have an impact on the bolus' solute or particle distribution, which may change the bolus' composition and characteristics.As shown in Figure 10, the appearance of the trapped bolus changes in the top area of the channel as the influence of the thermal slip parameter increases, whereas the number trapped boluses increases in the bottom region.In Figure 11, it is shown that when the concentration slip parameter increases, the size of the trapped bolus decreases in the top region of the channel while increasing in the bottom.The opposite behaviour is noted when nanoparticle parameter increases.According to Figure 12, the volume of the trapped bolus increases due to the increasing impact of nanoparticle slip parameter, whereas in the lower part, the trapped bolus decreases.

Conclusion
The study looks at the phenomena of double-diffusive convection making use of the Sisko nanofluid model.It illustrates the effects of induced magnetic field, viscous dissipation, and heat radiation in an asymmetric geometry with numerous slip conditions.The convective double diffusion phenomena are described by the Soret and Dufour parameters.Mathematical formulation of the proposed model is carried out in 2-dimensional and 2-directional flow.A group of nonlinear partial differential equations are generated by the mathematical modelling of fluid flow.Using Mathematica's built-in NDSolve program, the coupled nonlinear differential equations are numerically computed.Graphical data are shown to highlight the importance of various physiological features of flow amounts.The following are the key conclusions drawn from this investigation: • As the radiation parameter increases, the distribution of temperature decreases as a result of the system's significant heat radiation and thereby resulting in cooling effects.• An increase in the Brownian motion corresponds to an increase in the temperature distribution because when particles collide more frequently and strongly, some of their kinetic energy is transmitted to the suspended particles.As a result of the energy transfer, the particles' internal energy increases and their temperature rises.• Heat diffusion has a greater effect on the concentration profile as the Soret parameter increases.• An increasing impact of heat radiation causes the concentration profile to increase.• The nanoparticle volume fraction profile lessens as the Prandtl number's influence increases.• When a fluid's temperature changes due to thermal radiation, buoyancy effects occur that cause the fluid to rise to a higher level, which can increase the volume fraction of nanoparticles.• As the velocity slip rises, the trapped bolus shape and size are reduced in both the upper and bottom parts of the channel.• The volume of the confined bolus reduces in the upper part of the channel while boosting in the bottom as the concentration slip parameter rises.

(a), when the fluid is in the range x ∈ [−2.45, −2] and x ∈ [1,1.6], the velocity of the fluid rises owing to the increase in the influence of the non-Newtonian parameter, but when the fluid is at the channel's centre at x = −0.5, the maximum fluid velocity exists.Furthermore, as fluid approaches the regions x ∈ [−2.0, −0.6] and x ∈ [−0.6,1.0], the velocity begins to decrease due to the increasing behaviour of r.According to Figure 4(b), the velocity of fluid drops in the region x ∈ [−1.3,0.8] as the effect of velocity slip parameter (l 1 ) increases.Furthermore, similar behaviour of fluid velocity is noted in the regions x ∈ [−2.45, −1.3] and x ∈ [0.8,1.6].

Figure 7 (

Figure 7 (
a) illustrates that when the effect of the Prandtl number increases, the nanoparticle volume fraction profile decreases.From Figure 7(b), it is seen that the profile of nanoparticle volume fraction enhances when the impact of nanoparticle slip parameter increases.It is highlighted in Figure 7(c) that when the Brinkman number increases, the convective flow dominates.The fluid's nanoparticles may mix more effectively as a result of the enhanced flow.The outcome is a greater nanoparticle volume percentage because the nanoparticles are spread more uniformly.It is observed from Figure 7(d) that increasing the radiation parameter may result in considerable fluid heating or temperature gradients.As a result, thermal buoyancy forces may be produced, causing convective fluid motion.Increased convection promotes nanoparticle dispersion and mixing throughout the fluid resulting in a higher nanoparticle volume fraction.
