Stagnation Point Flow and Heat Transfer Through Porous Medium: Effects of Porosity and Magnetic Parameters on Stagnation Point Flow and Heat Transfer in a Porous Medium

Abstract

Tostudy the two-dimensional laminar boundary layer flow of viscousincompressible, electrically conducting fluid through porous medium near astagnation point. It is assumed that the velocity and temperature proportionalto the distance from the stagnation point. The numerical solution for the governingnon-linear momentum and energy equation has been obtained independently by aperturbation technique for small magnetic parameters. In this problem theeffect of porosity of the medium, surface velocity, Hartmann number, Prandtlnumber and Eckert number for velocity and temperature distribution have beendiscussed with graphical representation.
