RÉSUMÉ

This article presents diffusion-thermo and thermo-diffusion effects on unsteady magnetohydrodynamic, natural- convection heat and mass-transfer flow past an accelerated vertical porous plate under conditions of thermal radiation, variable temperature (T), and variable concentration (C). We solve governing equations pertinent to fluid flow by applying finite-difference schemes. Variations in velocity, T, and C are discussed and exhibited with the help of graphs. Numerical values for local skin friction (τ), Nusselt number, and Sherwood number are recorded and analyzed. Increasing values of Soret number (S0) result in augmented C, but C decreases under the influence of the Schmidt number. τ decreases with increasing values of S0.
