Soret and Dufour e ffects on viscoelastic boundary layer flow over a stretching surface with convective boundary condition with radiation and chemical reaction

In this article, we investigate the double di usive flow of a viscoelastic fluid on a stretching paper with convective boundary condition under the in fluence of thermal-di usion and di usion-thermo e ects, thermal radiation, internal heat generation or absorption, chemical reaction, and thermal radiation. The governing boundary layer equations are analytically solved by using Homotopy Analysis Method (HAM). Variations of the velocity, concentration, and temperature pro les for di erent values of physical parameters are graphically displayed and discussed. Numerical results of the local Sherwood number and the local Nusselt number are also tabulated. It is observed that the local Nusselt number increases on increasing the radiation parameter. The local Sherwood number increases on increasing the chemical reaction parameter.
