Fluid is considered in the influence of transverse magnetic field in the presence of radiation effect. Rosseland approximation is use to model the radiative heat transfer. The stream function splits into a Hiemenz and a tangential component. Using similarity variables, the governing partial differential equations are transformed into a set of three non-dimensional ordinary differential equations. These equations are then solved numerically using fifth order Runge-Kutta Fehlberg method with shooting technique. In the present reported work the effect of striking angle, radiation parameter, magnetic field parameter and the Prandtl number on flow and heat transfer characteristics have been discussed. The reported results are in good agreement with the available published work in the literature. Keywords: MHD, Oblique Stagnation-point, Heat transfer, Rosseland approximation. 1 INTRODUCTION The flow of an incompressible viscous fluid over a stretching surface is important in various processes.
