MHD FREE CONVECTIVE FLUCTUATING FLOW THROUGH A POROUS EFFECT WITH VARIABLE PERMEABILITY PARAMETER

In the present paper, we have studied MHD free convective two dimensional unsteadyviscous incompressible flows through a porous effect bounded by an infinite vertical porous plate with constant suction. The permeability of the porous medium fluctuates in time about a constant mean, and the viscosity of fluid is assumed to vary as a linear function of temperature. The flow is permitted under the influence of a uniform transverse magnetic field, whereas the induced magnetic field has little effect on the flow and can be neglected. The governing equations are solved by perturbation technique based on computer extended series solution.
