Abstract:

In this article, the effect of mixed convection on hydromagnetic non-aligned stagnation point flow of Casson fluid over a convectively heated stretching sheet has been examined. Effects of thermal radiation and partial slip are also taken into account. Using appropriate similarity transformations, the governing partial differential equations are transformed into a system of coupled nonlinear ordinary differential equations and solved numerically by shooting method along with Runge- Kutta-Fehlberg integration technique. The profiles of fluid velocity and temperature are plotted and analysed corresponding to various pertinent flow parameters such as magnetic parameter, stagnation parameter, mixed convection parameter, velocity slip parameter, radiation parameter, Biot number etc. Also, the skin friction and rate of heat transfer at the surface are computed and explained in detail. For positive and negative obliqueness, stream line patterns are also plotted. It is observed that the normal velocity increases with the rise of stagnation parameter whereas tangential velocity diminishes when mixed convection parameter is intensified. Also, the impact of stagnation parameter on fluid temperature is opposite to that of velocity slip parameter. Recent Publications 1.
