Effects of heat generation/absorption and thermophoresis on hydromagnetic flow with heat and mass transfer over a flat surface

Abstract

The problem of steady, two‐dimensional, laminar, hydromagnetic flow with heat and mass transfer over a semi‐infinite, permeable flat surface in the presence of such effects as thermophoresis and heat generation or absorption is considered. A similarity transformation is used to reduce the governing partial differential equations into ordinary ones. The obtained self‐similar equations are then solved numerically by an implicit, tri‐diagonal, finite‐difference scheme. Favourable comparison with previously published work is performed. Numerical results for the velocity, temperature and concentration profiles as well as for the skin‐friction coefficient, wall heat transfer and particle deposition rate are obtained and reported graphically for various parametric conditions to show interesting aspects of the solution.
