chtMultiRegionFoam channel cooling

razi.me05 · March 2, 2023, 10:40

Hi,

Currently, I am using OF-10. I want to simulate cooling of an Aluminum block by a channel inside. After checking the available BCs for the coupled/mapped wall it seems like temperatures are simply mapped between the two regions (solid/fluid). I'm particularly talking about turbulentTemperatureCoupledBaffleMixed. Now instead of simply mapping based on thermal conductivity (kappa) I need to use forced convection between the two regions. Is there any BC for convection in a coupled wall or I'll have to implement it? I need both solid and fluid to be resolved.

Thanks for any help in advance.
