Simultaneous effects of heat and mass transfer on time-dependent flow over a stretching surface

Abstract

This article deals with the combined effects of heat and mass transfer on the two-dimensional time-dependent flow of a second grade fluid bounded by a stretching surface. The present analysis takes into consideration the Soret and Dufour's effects in the presence of a chemical reaction. The governing equations for velocity, concentration, and temperature fields are derived. Using the homotopy analysis method, the solution of outcoming equations are computed. Graphical results for velocity, temperature, and concentration fields are reported and analyzed. © 2010 John Wiley & Sons, Ltd.
