Hi FOAMers
I'm a beginner in CFD and OpenFOAM in particular. Yet I managed to implement and solve a problem of an Ar-plasma being extracted into a vacuum chamber. The solution is stable, but the temperature seems to high. Short description: A vacuum chamber is held at 150 Pa and has an opening with a fixed pressure a 1 atm. The mesh is axi-symetric. The Ar-plasma is defined to be 5000 K and is not really a plasma, it's just hot Ar. A nice supersonic jet is forming in the vacuum. The problem with the jet is a more or less constant temperature. The hot Ar should cool down due to the radiation. But, I have no glue how to implement that into the definitions for rhoCentralFoam. Any ideas howto implement radiative cooling of the fluid? cheers Niko |
