Magnetohydrodynamic stagnation point flow past a porous stretching surface with heat generation

Chaudhary, Santosh ; Kumar, Pradeep

Abstract

A general analysis has been developed to study the two-dimensional, laminar flow of a viscous, incompressible, electrically conducting fluid near a stagnation point of a stretching sheet through a porous medium with heat generation in the presence of a magnetic field. The governing boundary layer equations have been transformed to ordinary differential equations by using suitable similarity variables. The solutions of momentum and energy equations have been obtained independently by a perturbation technique for a small magnetic parameter. The effects of various parameters such as magnetic parameter, porosity parameter, stretching parameter, Prandtl number, Eckert number and heat generation coefficient for velocity and temperature distributions along with local skin friction coefficient and local Nusselt number have been studied in detail through graphical and numerical representations.
