DOI 10.1515/nleng-2013-0014 Heat Transfer Analysis for Couple Stress Fluid over a Nonlin- early Stretching Sheet Najeeb Alam Khan,1; Fatima Riaz1 and Nadeem Alam Khan1 1 Department of Mathematical Sciences, University of Karachi, Karachi 75270, Pakistan Abstract. An investigation has presented to analyze the heat transfer in a boundary layer flow of an incompress- ible couple stress fluid over a nonlinear stretching sheet. The heat transfer problem have been analyzed for the two

casting, and glass blowing. Originally, the revolutionary work of boundary layer flow from a stretching sheet was premeditated by Sakiadis [ 1 ] and Erickson [ 2 ]. Later, Crane [ 3 ] extended the same [ 1 , 2 ] model work for 2-D flow for the stretching surface and reported the exact solution. Successively numerous investigators have further protracted the Sakiadis and Crane models for analysing suction or blowing problems [ 4 ], viscous dissipation effects [ 5 ], stagnation flows [ 6 ] and variable viscosity [ 7 ]. Conversely, in several stretching flow problems

1 Introduction The flow past a stretching sheet has several important engineering applications, namely, polymer processing unit of a chemical engineering plant, metal working process in metallurgy, hot rolling, wire drawing, glass fiber, and drawing of plastic films. Sakiadis [ 1 ], [ 2 ], [ 3 ] initiated the theoretical study of these applications by considering the boundary layer flow over a continuous solid surface moving with constant speed. Crane [ 4 ] studied the steady two-dimensional boundary layer flow caused by the stretching sheet which is an extension

. Kameswaran et al . [ 1 ] analyzed the effect of radiation on MHD Newtonian fluid over an exponentially stretching sheet. Mandal and Mukhopadhyay [ 2 ] studied the flow and heat transfer along a surface stretching exponentially and embedded in porous media with variable surface heat flux. Singh and Agarwal [ 3 ] considered the influence of non-uniform heat source/sink and variable thermal conductivity on the MHD flow and heat transfer over an exponentially stretching sheet in a porous medium saturated with Maxwell fluid.
