摘 要: | Natural convective heat transfer phenomena in porous media are very common in the energy conversion and energy utilization field. Study on these phenomena is an impor- tant branch of heat and mass transfer at the moment[1,2]. For theoretical analysis in early time, the Darcy model proposed many years ago was often used. However, great im- provements have been made to the Darcy model in recent years in order to more accu- rately describe and more widely reflect the objective reality[3―7]. The…
