Free convective MHD flow past a vertical plate through a porous medium with ramped wall temperature and concentration

Abstract

This study attempts to examine the ramped wall temperature and concentration of an unsteady free MHD, viscous, incompressible, electrically conducting fluid past a vertical plate through a medium of porous nature under thermal radiation. Sets of dimensional governing equations are considered by taking suitable assumptions, which are then transformed into non-dimensional forms. Non-dimensional equations are being solved analytically with the help of Laplace Transform method. Resultant effects of some parameters concerning the problem on temperature, velocity, concentration, coefficient of skin-friction, Nusselt number and Sherwood number are discussed through different graphs and are physically interpreted. From the graphs, results are found out and related interpretations are made.
