Effect of magnetohydrodynamic Casson fluid flow and heat transfer past a stretching surface in porous medium with slip condition

In this paper, we investigate the flow of magnetohydrodynamic Casson fluid over a linear stretching surface in porous medium with slip condition. The governing partial differential equations are reduced to non-linear ordinary differential equations with the aid of similarity transformation. The transformed equations and boundary conditions are then solved by using exact analytical method. The flow field is affected by the presence of physical parameters, such as Casson fluid parameter, magnetohydrodynamic parameter, velocity slip parameter, porosity parameter, and suction/injection, whereas the temperature field is additionally affected by magnetohydrodynamic, thermal radiation, Prandtl and Eckert numbers. The effects of the pertinent physical parameters on the velocity and temperature fields are presented through graphs and discussed. Skin friction and heat transfer coefficients are tabulated and analyzed.
