The computations are based on the finite-element-based control volume method for a moved grid, and the SIMPLER algorithm has been implemented. The physical model for the momentum conservation equation makes use of the Brinkman−Lapwood−Forchheimer-extended Darcy model for the porous matrix. The fluid structure and the heat transfer are analyzed for different Reynolds numbers, Darcy numbers, porosities, thermal conductivity ratios, and heat capacity ratios. %8 2011-11-10
