Hi,


I´m actually using:

Chemical Engineering module-->Flow with variable density-->Non-isothermal flow-->k-eps turbulent model

I´m trying to simulate a fluid in a clod plate, with the heat flux going into the cold plate from the top side.
I have gotten to simulate the water in the channel.
But in the new model I have to intoduce a air channel between the water channels to decrese the heat flux between them (like a resistance).The air is not flowing is like a hole with air that does not move.
The problem is that I´m using the turbulent model for the water. Should I include other model for the free convection of the air?

I´m using the 3.5a version of comsol.

Thanks in advance,

A. Jenkins
