CFD Simulation of Wall Effects in Flow Past a Square Cylinder in a Stationary and Moving Plane Channel
A numerical study on the steady state flow of an incompressible Newtonian fluid past a square cylinder confined in a rectangular channel by two plates has been carried out using CFX 10.0. Computations were carried out for two different boundary conditions of moving and stationary plates for a Reynolds number range between 0.1 to 200 and a blockage ratio ? in the range 0.0125 to 0.65. The flow parameters such as drag coefficient, length of recirculation zone were determined. From the results obtained it was found that drag coefficient decreased with an increase in Re for a fixed value of ?. For a given value of ?, the length of recirculation increases as the Re increases. An expression has been developed for the relation between drag coefficient and ?.
