FloWorks/Cosmos thermal board analysis
FloWorks/Cosmos thermal board analysis
(OP)
Basically, I am modeling a few key components on a board and doing a thermal analysis in an enclosure. I need to model the thermal resistance between the junction and the board and junction and the ambient so that I can accurately predict junction temperature (for reliability calcs)
I have theta j-a and j-c for some components. I have the component modeled and the board (simple, just a block). I was going to use J-C, multiple by surface area and use that for contact resistance between the part and the board. Then do the same with J-A for a convection coeff on the other 5 surfaces on the part.
Is this the right way to simulate this? Or a better way? Are there good "rules of thumbs" or ways to do this? thanks

Maybe try forum "Computational Fluid Dynamics CFD"?
