Buoyancy driven flow in a non-darcian, fluid-saturated porous enclosure subjected to uniform heat flux - A numerical study

The differences in existing porous medium flow models and their effect on flow and heat transfer are discussed. A fluid-saturated porous medium subjected to constant heat flux has been considered. The Galerkin finite element method coupled with the velocity correction procedure is used to solve a set of generalized porous medium equations. Results are presented for a wide range of Darcy and Rayleigh numbers. Copyright © 1999 John Wiley & Sons, Ltd.
