Flow past a vertical porous surface under fluctuating thermal and mass diffusion with MHD effects

Abstract

This paper is examined with reference to critical parameters in the case of free MHD convection flow on a vertical porous surface under the fluctuating thermal and mass diffusion. An attempt has been made to understand the effects of the various critical parameters that appear in field equations and their effects over velocity field. It is noticed that, the prandtl number and velocity are inversely related. Moreover, it is observed that as the prandtl number increases, there is a decrease in the velocity and also back flow is observed. Even when the pore size of the bounding surface is decreased significant change in the velocity profiles is seen. Moreover, it is noticed that the prandtl number and temperature are directly proportional to each other.
