Hi all,
I am dealing with a conjugate heat transfer problem for electronics cooling in a very small domain (compartment or enclosure) in FLUENT, with quite a complex geometry, and I am a little bit stagnated. I have been fighting with the mesh for a long time, and I think all problems related with skewness and quality are already solved. Also interfaces are correct. Still, I am having troubles for convergence. I suspect the problem is, as it is such a small domain, that a very high gradients for temperature and turbulence variables can be found at the outlet. However, I would like to avoid to extrude it farther out of the compartment... My outlet is, in a first approuch, a pressure-outlet. ¿Any idea on how could I treat this situation? I would appreciate very much any guess. Thanks! |

Size shouldn't be an issue.
Electronics cooling is generally laminar flows; large gradients and turbulent flows are extremely rare. Are you sure the problem is as tough as you make it seem? |
