Slip effects on the parametric space and the solution for boundary layer flow of casson fluid over a porous stretching/shrinking sheet

This investigation reports slip effects on the boundary-layer flow of a Casson fluid over a porous stretching/shrinking sheet. A self-similar ODE is first obtained for the governing PDEs and then the obtained ODE with appropriate boundary conditions is solved analytically. The effects of all the physical parameters on flow field are presented through figures and a table. It is found that there is a pronounced effect of slip on flow characteristics. Moreover, a unique solution exists for stretching sheet problem; whereas dual solutions exist for shrinking sheet case. Furthermore, feasible solution domains for physical parameters are obtained and discussed.
