Radiation and thermal-diffusion interaction on stagnation-point flow of Walters' B fluid toward a vertical stretching sheet

In this article, the behaviors of radiation and thermal-diffusion on Walters' B model toward a vertical stretching surface with volumetric heat generation/absorption are examined. The system of nonlinear ordinary differential equations which are responsible for the behaviors of momentum, energy and concentration equations in relation to Velocity f ' (eta), temperature theta(eta) and concentration null (eta) are obtained by befitting similarity transformation and solved with Homotopy-Analysis-Method(HAM). The behaviors of various partients are discussed by virtue of graphs and tables as well as the convergence of the series solution and the iterations. It is noticed among others that the presence of Weissengerg number makes the problem to exhibit non-Newtonian property which steeredup viscoelasticity via the tensile stress and lower the momentum layer while various values of thermal-buoyancy contributes to the cooling of the sheet with adverse effect in Technological field for cooling of an electronic components and other materials.
