Effects of Slip on MHD Flow of a Dusty Fluid over a Stretching Sheet through Porous Space

Abstract

In this paper the effect of slip on the MHD flow of a dusty fluid over a porous stretching sheet in a porous medium is studied. The equations are modeled using Darcy’s law and simplified by using boundary layer approximations. The coupled system of nonlinear ordinary differential equations is obtained by employing similarity transformations. These coupled equations are then solved analytically by perturbation method and numerically by Runge–Kutta method of order four. The results are presented graphically and influence of various parameters of interest on the velocity of both fluid and dust phases and skin friction coefficient is analyzed. The comparison of analytical and numerical solutions is given and found in an excellent agreement.
