Unsteady MHD Mass Transfer Flow past a Temporarily Accelerated Semi-infinite Vertical Plate in Presence of Thermal Diffusion with Ramped Wall Temperature

Received: 27 August 2018 Accepted: 22 November 2018 An exact solution to the problem of transient MHD mass transfer flow past a temporarily accelerated vertical plate with ramped wall temperature has been presented. The novelty of the present work is to analyze the influence of Soret effect on the flow and transport characteristics in the presence of thermal radiation and ramped wall temperature. The governing equations are solved by Laplace transform technique in closed form. The expressions for the velocity, temperature and concentration fields as well as skin friction, rates of heat and mass transfer in terms of Nusselt number and Sherwood number are obtained in non dimensional form. Influence of the physical parameters on the above fields which involved in the problem are demonstrated through graphs. It is seen that fluid velocity and concentration increase with the increase in Soret number.
