• HEAT AND MASS TRANSFER EFFECTS ON MHD BOUNDARY LAYER STAGNATION-POINT FLOW OVER A NONLINEAR STRETCHING/SHRINKING SHEET IN POROUS MEDIA
Abstract
An analysis is made to study two dimensional incompressible MHD boundary layer stagnation-point flow over a nonlinear stretching/shrinking sheet in porous media. The stretching/shrinking velocity and the external flow velocity imply normal to the stretching/shrinking sheet are assumed to, where m is a constant and x is distance from the stagnation point. The governing partial differential equations are transformed into ordinary differential equations by means of similarity transformations. The resulting non-linear ordinary differential equations are solved using Runge-Kutta fourth order method along with shooting technique. The velocity and temperature distributions are discussed numerically and presented through graphs. The numerical values of Skin-friction coefficient and Nusselt number at the stretching/shrinking sheet are derived, discussed numerically for various values of physical parameters and presented through tables.
