Heat transfer considering Thermal-Contact-Resistance

ahmmedshakil · June 18, 2016, 08:35

Hi,

I'm trying to solve a problem of heat transfer between two solids, and I've to consider the Thermal-Contact-Resistance for the simulation. For the this multi-region problem, I'm using chtMultiRegionFoam solver. I'm wondering if anyone worked and considered the issue of Thermal-Contact-Resistance. It will be great help if anyone can advise me how to incorporate Thermal-Contact-Resistance in the interface boundary of the two contacting solids.

Thanks in advance.

Hi Mohammad,

I have good news for you, both turbulentTemperatureRadCoupledMixed and turbulentTemperatureCoupledBaffleMixed allow you to account for thermal contact resistances between your regions.

I hope it helps.

Best regards,

Alex

Some basic tutorials are also resolved step by step in the web. If you are interested in these matters, you are invited to come in!
