MIXED CONVECTION MAGNETO HYDRODYNAMIC HEAT AND MASS TRANSFER ON MELTING FROM A VERTICAL PLATE EMBEDDED IN POROUS MEDIUM UNDER THE INFLUENCE OF SORET AND DUFOUR EFFECTS

Abstract

A mathematical model is developed to examine the combined effects of Soret and Dufour on mixed convection magneto hydrodynamic (MHD) heat and mass transfer on melting from a vertical plate saturated in porous medium. The governing boundary layer equations for momentum, energy and species transfer are transformed to a set of non-linear ordinary differential equations by using similarity solutions which are then solved numerically based on shooting algorithm with Runge–Kutta–Fehlberg integration scheme over the entire range of physical parameters with appropriate boundary conditions. The influence of Soret number and Dufour number and magnetic parameter on velocity, temperature and concentration fields are studied graphically.
