Numerical Simulation of MHD Hiemenz Flow of a Micropolar Fluid towards a Nonlinear Stretching Surface through a Porous Medium

Abstract

In this paper, the two-dimensional boundary layer problem of Hiemenz flow (two-dimensional flow of a fluid near a stagnation point) of an incompressible micropolar fluid towards a nonlinear stretching surface placed in a porous medium in the presence of transverse magnetic field have been examined. The resulting non-linear differential equations governing the problem have been transformed by a similarity transformation into a system of non-linear ordinary differential equations which are solved numerically by Element Free Galerkin method. The influence of various parameters on the velocity, microrotation, temperature and concentration is shown in the graphs. Some of the result has been compared with Finite Element Method. Finally, excellent validation of the numerical results has been achieved with the earlier steady state results of Nazar et al. [2] for local skin friction [ ]
