Hello there:
I am trying to use reactingFoam to simulate NG injection / ignition / combustion in a combustion chamber. When it injects (even at low velocity), the expansion causes temperature to go below the lower JANAF range (which is 200 K). I tried to trick reactingFoam by changing the JANAF temperautre bounds (in constant/thermo.properties) to 0K to 50000K, but it looks like some kind of downward spirl, and the solver would eventually reach temepratures beyond the bounds. Is there a way to use something other than the JANAF tables given here? Thanks, Bart. |
