摘要：
In this paper, we present an investigation for MHD stagnation-point flow of a nanofluid past a heated porous stretching sheet with suction or blowing conditions and prescribed surface heat flux. The effects of Brownian motion and thermophoresis occur in the transport equations. The governing coupled partial differential equations are non-dimensionalized and solved analytically by homotopy perturbation method (HPM) employing Pade technique. The effects of involved parameters (magnetic number, porosity parameter, velocity parameter, surface heat flux, suction or injection parameter, Prandtl number, Lewis number, Brownian motion, thermophoresis) on velocity, temperature and concentration profiles are presented graphically and analyzed. A comparative study between present results in a limiting sense with the already published results revealed an excellent agreement. (C) 2014 Elsevier B.V. All rights reserved.
