MIXED CONVECTION IN POROUS MEDIA WITH INTERNAL HEAT SOURCES
Bian Wei Wang Buxuan(Tsinghua University)
In this paper, a mixed convection in a vertical porous channels with internal heat sources is numerically studied. The distribution of velccity, temperature and heat flux at various conditions are calculated, the results show that the flow reversal zones can appear near the two walls and these zones will move upstream with the increasing intense of the internal heat sources. The criterion for judging flow reversals can be obtained through FDF theory.
