摘要

We analyse a fully developed free corrective flow of an electrically conducting viscous incompressible fluid through a saturated porous medium in a vertical channel using Brinkman's model taking into account the viscous, Darcy and Ohmic dissipation. A uniform magnetic field of strength H_o is applied normal to the boundary. The non-linear equations governing the flow and heat transfer have been analysed by using the finite element method. The velocity, temperature and Nusselt number are evaluated to the second order and their behaviour is discussed for variations in the governing parameters. We observed that the dissipation reduces velocity and suction Reynolds number enhances u.
