The effect of Soret and Dufour on the Transient solution of second grade fluid flow and heat transfer past a vertical infite plate

Abstract

This study discuss transient state solutions to a system of a coupled equations; which address the continuity, momentum, energy and specie concentration equations for a second grade fluid. The Adomian decomposition method was used to solve the problem for the flow geometry of a vertical infinite plate. The Soret and Dufour effects were investigated in terms of velocity, temperature and specie concentration profiles. The findings show that higher values of the Prandtl number, Soret and the suction parameter flow velocity, heat transfer temperature an concentration profiles while the Dufour number reinforces fluid flow velocity and fluid temperature fields.
