Simultaneous Effects of MHD and Thermal Radiation on the Mixed Convection Stagnation-Point Flow of a Power-Law Fluid

Magnetohydrodynamic (MHD) mixed convection stagnation-point flow and heat transfer of power-law fluids towards a stretching surface is investigated. The homotopy analysis method (HAM) is used in finding the series solution for a nonlinear problem. Closed form solutions for velocity and temperature fields are presented in the limiting cases. Graphical results are shown. It is found that velocity and temperature are decreasing functions of power law index. Numerical computations for shear stress coefficient and local Nusselt number are reported. The present results are also compared with the existing numerical solution in a limiting sense.
