Heat And Mass Transfer on Flow Past an Accelerated Plate Through Porous Medium with Variable Temperature and Mass Diffusion in Presence of Heat Source/Sink

Abstract

A study to look at how heat and mass transfer affect unsteady MHD flow across an accelerated plate with changing temperature and mass diffusion in the appearance of a heat source (or sink) through a porous medium is presented. Initially, the temperature and concentration of the fluid and plate are considered to be the same at t′ ≤ 0. At t′ > 0, an impulsive uniform acceleration A is applied to the plate in a vertical upward direction. The non-dimensionalised governing equations defining the flow problem are solved using Laplace transform approach. Effect of various physical quantities involved in the velocity, concentration, temperature, the rate of heat transfer and also the rate of mass transfer are investigated through graphs and tables and discussed.
