  • Boundary element method for natural convection in a porous cavity using Forcheimer model
    Jecl, Renata ; Škerget, Leopold
    The use of the Forcheimer model for analyzing the convective flow in a porous cavity is presented emphasizing investigation of the effect of the additional (Forchheimer) inertia term in momentum ... equation on the velocity and global heat transfer through the cavity. The effects that this term have upon the engineering parameters of interest for the case of a fluid saturated media, is known to be minimal but was not confirmed yet with the use of the boundary element method (BEM) or any of its extension. Therefore the numerical solution of the problem of natural convection in porous cavity using boundary domain integral method (BDIM) is presented, where the velocities and the total heat transfer are calculated for different modified Rayleigh and Darcy numbers and solutions are compared with published results obtained with the Brinkman model.
