Forced heat transfer for pulsating flow in composite porous/fluid system

The present work involves the numerical simulation of forced pulsating flow into a cylinder containing simultaneously fluid region, porous region and fluid region and the associated transport process. The cylinder wall is adiabatic in the fluid regions and at constant heat flux in the porous region. A general model for the momentum equation was employed. The mathematical model for energy transport was based on the local thermal equilibrium assumption. The control volume-based finite element method (CVFEM) is used for solving the differential system equations with an unequal order velocity-pressure interpolation. The numerical results of the flow and the temperature fields are presented and discussed. A comprehensive analysis of the influence of the amplitude pulsation, the frequency pulsation, the thermal conductivity ratio and the heat capacity ratio is presented.
