Mixed convection stagnation point flow of casson fluid with convective boundary conditions

The mixed convection stagnation-point flow of an incompressible non-Newtonian fluid over a stretching sheet under convective boundary conditions is investigated. Mathematical formulation is presented for a Casson fluid. The resulting partial differential equations are converted into the ordinary differential equations by the suitable transformations. The velocity and temperature profiles are computed by employing the homotopy analysis method. The plotted graphs illustrate the flow and heat transfer characteristics and their dependence upon the embedded parameters. Numerical values of skin-friction coefficient and Nusselt number are given and examined. Comparison of the present results with the existing solution is also given.
