Numerical study on MHD radiating and reacting unsteady slip flow past a vertical permeable plate in a porous medium

This paper examines the unsteady hydro-magnetic boundary layer flow of a reacting and radiating electrically conducting fluid past a slippery permeable vertical plate embedded in a porous medium. The governing partial differential equations are obtained and tackled numerically via Galerkin finite element method. Pertinent results with respect to the effects of emerging thermo physical parameters on the velocity, temperature and concentration fields together with skin-friction, Nusselt number and Sherwood number are elucidated graphically and in tabular form. Numerical validation of the present work special case results with the one already in the literature shows an excellent agreement. It is found that buoyancy forces enhanced the momentum boundary layer while magnetic field and radiative heat absorption lessen it. Both heat and mass transfer rates diminished with a rise in the rate of chemical reaction.
