• MHD FREE CONVECTIVE HEAT AND MASS TRANSFER FLOW PAST A LINEARLY ACCELERATED PLATE WITH VARIABLE TEMPERATURE AND MASS DIFFUSION
Abstract
An investigation of MHD free convective heat and mass transfer flow of a viscous, incompressible and radiating fluid past a linearly accelerated transfinite vertical porous plate in the presence of heat absorption, first order chemical reaction is carried out. The governing partial differential equations are converted into non-dimensional form and evolved analytically by applying Laplace transform technique in two cases namely (i) exponentially variable surface temperature (EVST) and linearly variable surface concentration (LVSC) and (ii) linearly variable surface temperature (LVST) and exponentially variable surface concentration (EVSC). Further the expressions for skin friction, Nusselt number and Sherwood number are also derived. The effects of system parameters entering into the present problem on flow quantities such as fluid velocity, fluid temperature and species concentration are depicted graphically. Numerical values of skin friction, Nusselt number and Sherwood number at the plate are presented in tabular form for various values of relevant flow parameters.
