RÉSUMÉ

The aim of this paper is to investigate the effects of Joule heating on an unsteady magnetohydrodynamic (MHD) free convective heat and mass transfer flow past a moving vertical plate in a porous medium in the presence of chemical reaction. The governing partial differential equations are reduced to a system of self-similar equations using the similarity transformations. The resultant equations are then solved numerically using the fourth-order Runge-Kutta method along with a shooting technique. The effects of governing physical parameters on velocity, temperature, and concentration as well as skin-friction coefficient, Nusselt number, and Sherwood number are computed and presented in graphical and tabular forms. Comparisons with previously published work are performed, and the results are found to be in excellent agreement.
