Hydromagnetic Nanofluid Flow in the Presence of Radiation and HeatGeneration/Absorption Past an Exponential Stretching Sheet with SlipBoundary Conditions Using HAM

Abstract

This paper considers the theoretical problem of hydrodynamic and slips boundary conditions over an exponential stretching sheet in the presence of radiation and heat generation/absorption. Similarity solutions are obtained from the governing boundary layer equations for different various of slip parameters, exponential parameter, magnetic field parameter, radiation parameter, heat source parameter, thermophoretic parameter and porosity parameter. The resulting couple system of equations which is highly nonlinear ordinary differential equations are solved semianalytically using homotopy analysis method (HAM). Numerical results are obtained for non-dimensional governing parameters on skin friction, heat and mass transfer coefficient in the presence of suction. Comparison with published results seen in literature is in perfect agreement.
