Abstract

This article is focused on the effectiveness of variable viscosity and variable thermal diffusivity on steady MHD heat and mass transfer flow over a semi-infinite porous inclined plate in the presence of thermal radiation and thermophoresis. The governing fundamental equations are transferred into a system of nonlinear similar ordinary differential equations, which are solved numerically by using Chebyshev pseudospectral method. Favorable comparisons with previously published work are performed and the results are found to be in very good agreement. Numerical results for the dimensionless velocity, temperature and concentration profiles as well as for the skin-friction coefficient, wall heat transfer and particle deposition rate are obtained and displayed graphically for pertinent physical parameters to show interesting aspects of the solutions.
