EFFECT OF THERMOPHORESIS PARTICLE DEPOSITION ON AN UNSTEADY FREE CONVECTIVE HEAT AND MASS TRANSFER IN A WALTERS-B FLUID PAST A SEMI INFINITE VERTICAL PLATE WITH RADIATION AND HEAT SINK/SOURCE

Abstract

 The effect of thermophoresis particle deposition on an unsteady free convective heat and mass 
transfer in a radiating Walters-B fluid along a semi-infinite vertical plate with heat sink/source is analyzed. The 
governing boundary layer equations are solved by an efficient, accurate and unconditionally stable finite 
difference scheme of the Crank-Nicolson type. The behavior of the velocity, temperature and concentration, 
the local skin-friction, Nusselt number and Sherwood number are computed for variations in the governing 
parameters.
