A1 Salama, Amgad A1 Abbas, Ibrahim T1 VISCOUS DISSIPATION EFFECT ON NATURAL CONVECTION IN A FLUID SATURATED POROUS MEDIUM JF Journal of Porous Media JO JPM YR 2010 FD 2010-11-24 VO 13 IS 11 SP 989 OP 997 K1 dissipation K1 porous medium K1 natural convection K1 finite-element method K1 non-Darcy AB This paper considers the problem of viscous dissipation effects on non-Darcy natural convection over a vertical flat plate embedded in a fluid-saturated porous medium. Forchheimer extension is considered in the flow equations and its contribution to viscous dissipation is considered in the energy equation. The nondimensional governing equations are solved, numerically, by the finite-element method (FEM). The resulting nonlinear integral equations are linearized and solved using Newton-Raphson iterations. Numerical results for the details of the stream function, velocity and temperature contours, and profiles as well as heat transfer rates in terms of the Nusselt number, are presented in graphs.
