Abstract

Forced convection in channels filled with packed beads with internal heat source was numerically analyzed by using the extended Darcy model for the flow and energy conservation equations with nonthermal equilibrium (NTE). The temperature difference between the matrix and fluid phases was discussed with three dimensionless parameters (Re~p~, H/d~p~, and k~s~/k~f~). It is concluded that the thermal equilibrium assumption may be adopted for the situation when the solid conduction dominated over the convection or when the heat transfer coefficient between the two phases is large at large Re~p~. The Nusselt number at the wall with the variation of Re~p~ for different k~s~/k~f~ was also investigated. © 2001 Scripta Technica, Heat Trans Asian Res, 30(3): 213–221, 2001

## Abstract In this paper, the differential transform method (DTM) was applied to heat transfer of a micropolar fluid through a porous medium with radiation. The governing equations can be written as a system of nonlinear ordinary differential equations. The approximate solutions of these equations
