ABSTRACT

The aim of this paper is a numerical simulation of a forced pulsating laminar flow into a cylinder partially filled with a porous medium and the associated transport process. The porous substrate is attached to the inner side of the cylinder wall, which is exposed to a constant heat flux. The flow within the porous domain is modeled by the Brinkman−Lapwood−Forchheimer-extended Darcy model. The mathematical model for energy transport is based on the local thermal equilibrium assumption.
The control volume-based finite element method (CVFEM) is used for solving the differential equations system with an unequal order velocity-pressure interpolation. The effects of the Darcy numbers, the porous layer thickness, the pulsation amplitude and frequency, the thermal conductivity ratio, and the heat capacity ratio are investigated.
