Mixed Convection Stagnation Point Flow of Casson Fluid with Convective Boundary Conditions

Abstract

Casson fluid flow has many practical applications food processing, metallurgy, drilling operations and bio-engineering operations. In the present paper we investigate the mixed convection stagnation-point flow of an incompressible non-Newtonian fluid over a stretching sheet with magnetic field under convective boundary condition. The resulting partial differential equations are converted into the ordinary differential equations by the suitable transformations. The velocity, temperature and concentration 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, Nusselt number and Sherwood number are given and examined. Comparison of the present results with the existing solution is also given.
