Effect of Nonlinear Thermal Radiation on Magnetohydrodynamic Stagnation Point Flow of Williamson Fluid Induced by Nonlinear Stretching Sheet in the Presence of Non Uniform Heat Generation/Absorption

This paper deals with effect of nonlinear thermal radiation on MHD stagnation point flow of Williamson fluid induced by nonlinear stretching sheet. Non uniform heat generation/absorption is considered. The governing partial differential equations are transformed into coupled nonlinear ordinary differential equations by using suitable similarity transformations. The resulted ordinary differential equations are solved numerically using the finite difference technique namely Keller Box method. Effects of various physical parameters on velocity, temperature and concentration profiles are investigated. Numerical values for local skin- friction, local Nusselt number, and local Sherwood number are computed for different physical parameters. The results are presented in graphical and tabular forms. From numerical results, some inferences are drawn.
