INTERNATIONAL JOURNAL OF NUMERICAL METHODS FOR HEAT & FLUID FLOW
A numerical simulation of the fully developed forced convection in a circul
ar duct partly filled with a fluid saturated porous medium is presented. Th
e Brinkman-Forchheimer-extended Darcy equation is used to describe the flui
d flow in the porous region. The energy equation for the porous region acco
unts for the effect of thermal dispersion. The dependence of the Nusselt nu
mber on a number of parameters, such as the Reynolds number, the Darcy numb
er, the Forchheimer coefficient, as well as the thickness of the porous reg
ion is investigated. The numerical results obtained in this research are in
agreement with published experimental data.
