Analysis of Casson Flow Through Parallel and Uniformly Porous Walls of Different Permeability

The present study deals with a steady twodimensional Casson in-compressible fluid flow in a channel due to non-uniform suction or injection through its porous walls. The constitutive equations are reduced to a nonlinear ordinary differential equation using similarity transformation with appropriate boundary conditions. Now, the modeled equation is solved using Homotopy Perturbation method (HPM) and by an effective finite difference method (FDM). The results obtained for velocity, skin friction at the upper and lower walls are displayed in the form of figures and tables. It is interesting to note that the results are in good agreement.
