Soret Effect Through a Rotating Porous Disk of MHD Fluid Flow

Abstract

The present study attempts to investigate numerically the problem due to rotating porous disk of MHD fluid flow with Soret effect using Darcy-Forchheimer model in a steady laminar Newtonian fluid. By using similarity transformation the governing equations of continuity, momentum, energy and concentration are converted into a system of nonlinear ODE’s. Matlab’s built in solver bvp4c has been employed to solve numerically the coupled ODE’s. Numerical results are obtained for velocity (radial, axial and tangential), temperature and concentration profiles for various parameters and are illustrated graphically. The effect of suction parameter on the radial and tangential skin friction coefficients and rate of heat transfer are obtained and compared with the one available in literature. The results are found to be in good agreement. Numerical values of Skin-friction coefficient, Nusselt number and Sherwood number are obtained for different values of parameter.
