Hi,
I haven't solve it but there seems to be a problem with the fluid flow in porous media: I've tried to make turbulent porous media flow and it didn't work.
My geometry is something like 10 rectangles one above the other. In the first rectangle i have low Re k-epsilon turbulence coupled with heat transfer and transport of diluted species, in the above rectangle i have porous media flow coupled with heat transfer and transport of diluted species and the above again low Re.... and so on.
I'm simulating the air flow in a solar dryer for fruits (the porous media). The air is flowing only due to density gradient (free convection). Coupled with the heat loss due to evaporation of water from fruits and with the moisture taken from fruits.
Try (if you have a similar case) not to make the porous media flow turbulent (i haven't try it yet - didn't had the time - yesterday I've posted the message)
If i find something new I'll let you know
Good luck,
Viorel
