MHD Mixed Convection Flow and Heat Transfer in a Porous Medium

摘要

The effects of a steady two-dimensional laminar MHD mixed convection flow and heat transfer against a heated vertical semi-infinite permeable surface in a porous medium are discussed. The coupled nonlinear partial differential equations describing the conservation of mass, momentum, and energy are solved by a perturbation technique. The results are presented to illustrate the influence of Hartmann number (M), Prandtl number (Pr), permeability parameter (K-p), suction/blowing parameter (f(w)), heat generation/absorption coefficient (phi), and mixed convection or buoyancy parameter (gamma). The effects of different parameters on the velocity and temperature as well as the skin friction and wall heat transfer are discussed with the help of figures.
