Hi,
I try the first time chkMultiRegionFoam with a simple example. Two circular fluid bodies separated by a pipe (as you find it in an double jacket heat exchanger), flow in different directions and one fluid transfer heat ,through the separting piece of pipe, to the other. Now I try to figure out the T boundary in the 0-folder.

There is one patch fluidint_to_pipe and I do not know which would be the suitable condition for that. I didn't find any tutorial aswell which I could take as a template.

Can somebody give me a hint how to proceed ?

Thx a lot.

Hello,

Region interfaces usually use one of the following boundary conditions for T:

• compressible::turbulentTemperatureCoupledBaffleMix ed;
• compressible::turbulentTemperatureRadCoupledMixed;

Depending on the version you are using, you can run some of the chtMultiRegionFoam tutorials to have examples :

• OpenFOAM foundation (openfoam.org): https://github.com/OpenFOAM/OpenFOAM...ultiRegionFoam
• ESI-OpenCFD (openfoam.com): https://develop.openfoam.com/Develop...ultiRegionFoam

Yann
