Hey, everyone, I'm new to the OpenFOAM and I met some difficult problems.
I'm working on a very low pressure reactor by using the reactingFoam. Since the reactor works on a 190Pa pressure and 1700K and it has a very very thin injector, I calculated that the inlet velocity becomes about 1400m/s After I tried this value(disables all reactions), it diverged soon So I think that may be you can give me some advise on this case Now I set the pressure BCs as outlet { type fixedValue; value uniform 190; } inlet01 { type fixedValue; value uniform 190; } and I set velocity BCs as outlet { type inletOutlet; value $internalField; inletValue uniform ( 0 0 0 ); } inlet01 { type fixedValue; value uniform (0 1339 0); } Besides, can reactingFoam handle such a low pressure case? Or should I choose other solvers? Thank you! Hope for the helps |
