Investigation of a double diffusive magnetohydrodynamic mixed convective flow along an inclined flat plate in a porous medium

Abstract

An analysis is performed to study the momentum, heat and mass transfer characteristics of Magnetohydrodynamic mixed convective flow along an inclined flat plate in a porous medium on the basis of boundary layer approximations, neglecting and including the effect of thermodiffusion respectively. The fluid is assumed to be steady, incompressible and dense, and a uniform magnetic field is applied normal to the direction of the flow. A Similarity transformation is used to transform the momentum, energy and concentration equations under consideration into coupled nonlinear boundary layer equations which are then solved numerically using the Runge-Kutta sixth-order integration scheme together with Nachtsheim-Swigert shooting iteration technique. The behavior of the velocity, temperature, concentration, local skin-friction coefficient, local Nusselt number and local Sherwood number for different values of relevant parameters have been computed and the results are presented graphically, and analyzed thereafter. The validity of the numerical methodology is checked by comparing the results obtained for some specific cases with those available in the literature, and a comparatively good agreement is reached.
