Description
The finite element method is applied to study the Benard stability problem in horizontal porous layers. The geometry considered is a two dimensional rectangular box of dimensions H and L. Non-Darcian effects due to viscosity and convection are introduced through the use of the Darcy-Brinkman model to relate the velocity of the fluid to the imposed pressure gradient. The value of Darcy number is varied from 0.1 to 0.0001 while the aspect ratio is changed from 2 to 10. It is found that the critical value of Rayleigh number increases with Darcy number. In this paper numerical predictions of dimensionless heat transfer rates are compared
