Abstract

The steady heat transfer of fluid counter flow through porous medium is studied by using thermal non-equilibrium method, the energy equation of the porous frame solved by fluidizing the porous frame method. First the correctness of simulation is validated by satisfying the energy conservation law. Then the temperature profiles of fluid and porous frame are discussed. At last the effects of porosity, particle diameter and fluid superficial velocity to the heat transfer intensity and energy efficiency are compared.
