| Izvleček: | The main purpose of this work is to present the use of the boundary element method (BEM) for analyzing the convective flow in a square porous cavity heated from the side. The flow is modelled by Brinkman-Forcheimer momentum equation (Forcheimer model) to investigate the effect of the Forcheimer inertia term on the global heat transfer through the cavity. The effect this term has on the engineering parameters of interest for the case of a fluid saturated medium is known to be minimal, but has not been confirmed yet with BEM or any of its extensions. The numerical solution of the problem (velocity, vorticity, temperature and rates of heat transfer) is obtained for different Rayleigh and Darcy numbers. The results are compared with the Brinkman extended Darcy momentum equation (Brinkman model). |
