Forced Convection Heat Transfer with Evaporation in a Heat Generating Porous Medium
RESUMO
A numerical investigation of internal forced convective flow with boiling through a duct filled with a heat generating porous medium is carried out. At a first stage, inertial as well as variable porosity effects are considered using a homogeneous, two-phase flow model and the BrinkmanForchheimer extended Darcy model. The capillary effects and liquid-vapor slip are considered next using the multiphase mixture model (MMM). Nonlocal thermal equilibrium between the flowing fluid and the solid matrix is accounted for in each case using two energy equations. The results presented in this work provide detailed information on the influences of wall channeling and capillary effects on velocity and temperature fields in both subcooled and boiling regions. The vapor production process Is studied for various values of the heat generation rate. To end, comparisons are made between the two approaches used in this study.
