The governing equation of the model namely; continuity, momentum, energy and concentration equation are non-dimensionlised and solved using perturbation techniques. The numerical results are presented graphically and effects of material parameters have been discussed.enFree convectivecouette flowVariable suctionPermeabilityDissipating fluidMass transfer.Article
