RÉSUMÉ

An analysis is carried out to study the mass transfer in the MHD flow for two viscoelastic fluids over a permeable shrinking sheet through a porous space in the presence of chemical reaction. The reaction of species is to be taken as nth-order homogeneous chemical reaction of constant rate. The resultant nonlinear partial differential equations are reduced to the system of nonlinear ordinary differential equations by using similarity transformations. The purely analytic solution of velocity and the concentration fields are obtained by means of the homotopy analysis method (HAM). The influences of the involving parameter on the velocity and the concentration profiles are shown through graphs and discussed in detail. The numerical values of the skin-friction coefficient and the surface mass transfer for various parameters are also given in tabular form. Comparison of both analytic and exact solutions is given and found in good agreement.
