Airpak: Problems with heat flow contour conditions

I am working with Airpak. I'm analysing the cooling of a transformer substation. So I have modeled a transformer. It is formed by a cube and some wings or blades ( I have put them in the 4 lateral walls of the cube)for transferring the heat. I have some problems: 1- I have 74 wings or blades. So the hexaedrical mesh is very large 2- I put a boundary condition of heat flow for each blade (each one must transfer 113.5 W). I obtain the solution and I obtain a full report ofa the heat flow for the blades but there is something wrong because I obtain that some blades transfer only 50 w approx. and other transfer more than 200 w.
I have some doubts. Can I have problems with the convergence? Problems with modeling the blades like 2D sources? |
