Abstract: An investigation is carried out to study the three-dimensional unsteady incompressible Couette flow of a visco-elastic fluid through a porous channel bounded by two horizontal infinite parallel plates in presence of heat and mass transfer. The second-order Rivlin-Ericksen fluid model is taken throughout the study. Approximate solutions for velocity, temperature, concentration and other flow characteristics of the problem have been obtained by using regular perturbation technique. The influence of different pertinent parameters on the flow region has been discussed through graphical illustrations. Newtonian results are found to come out as limiting cases of the present analysis.
