摘要：

Hornotopy analysis method (HAM) is employed to investigate the momentum, heat and mass transfer characteristics of MHD natural convection How and heat generation fluid driven by a continuously moving permeable surface immersed in a fluid saturated porous medium. The Solution is found to be dependent on several governing parameters, including the magnetic held strength parameter, Prandtl number, Darcy number, the dimensionless inertia coefficient, the dimensionless heat generation/absorption coefficient and the dimensionless suction/blowing coefficient. A parametric Study of all governing parameters is carried out and representative results are illustrated to reveal a typical tendency of the solutions. Representative results are presented for velocity and temperature distributions as well as the local friction coefficient and local Nusselt number. Finally, a proper discussion is derived on the obtained results and some remarkable conclusions are mentioned. (C) 2008 Elsevier B.V. All rights reserved.
