REG POROUS MEDIA HEAT TRANSFER

Rashmi Venkat

Dear All,

I am doing a porous media simulation where in my geometry has around 13 continuous porous region's and I have given the pressure drop in each and every region along with the energy values [ for heat transfer consideration ] . My simulation BC's are inlet mass flow rate and pressure outlet along with heat transfer.

This is the overview of the problem domain. My query is that, I am not getting the effective heat transfer in the region's of the porous domain. The temperature is not raising to the value which was obtained thru experiments. It is not even nearing to that value. It's showing very low temperature rise.

What might be the reason for this. ??????????? Is there anything wrong in the BC's ...... I have used K-epsilon, Superficial velocity formulation, and the domain mesh size is 13 lac.

I request some ppl to help me out in this issue with details.

Thank you Rashmi Venkat
