Impact of radiation and chemical reaction on stagnation-point flow of Hydromagnetic Walters' B fluid with Newtonian heating

摘要

In this article, two-dimensional boundary layer flow describing the impact of radiation and chemical reaction on stagnation-point flow of Hydromagnetic Walters' B fluid over a stretching surface is studied. The corresponding partial differential equations are converted to ordinary differential equations through the appropriate transformation variables and solved by Homotopy Analysis Method. The embedded parameters are discussed on dimensionless Velocity f' (η), Temperature θ(η) and Concentration O(η) profiles as well as tables for the Skin-friction, Nusselt number and Schwood number. The result reveals among other that the presence of Newtonian heating ( γ ＞ 0) magnifies temperature distribution and as a result, the quiescent fluid experiences thermal effect which play an important role in drying of the component while large values of radiation parameter pioneer radiative flux which magnifies the polymeric flow.
