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 ... Read more

The present paper considers a numerical study of the non-Darcy natural convection over a vertical flat plate in a fluid-saturated porous medium. Forchheimer extension is considered in the flow equations. The nondimensional governing equations are solved by the finite element method. The resulting nonlinear integral equations are linearized and solved using the Newton− Raphson iteration. The finite element implementations are ... Read more
