STUDY OF HALL AND SORET EFFECT ON MHD FLOW WITH A RAMPED PLATE TEMPERATURE OF AN EXPONENTIALLY ACCELERATED VERTICAL PLATE EMBEDDED IN A POROUS MEDIUM

Abstract

The present literature deals with the study of MHD flow of an incompressible viscous electrically conducting fluid along an exponentially accelerated infinite vertical plate in a rotating system. The effects of thermodiffusion, thermal radiation and Hall current, are analysed with ramped and isothermal plate conditions. The non-dimensional coupled partial differential equations of the model are solved analytically by using Laplace Transform method with the help of Heaviside step function; thus the expression for velocity field, temperature field, concentration field, skin friction coefficient, Nusselt number and Sherwood number are obtained. The influence of physical parameters such as m (Hall parameter), Sr (Soret number), K (Darcy permeability), λ (exponential parameter), Ω (rotation parameter) and R (radiation parameter) on these fields are discussed in detail through graphs.
