I simulate the propane-air mix
I simulate the propane-air mixtures combustion with XiFoam.
I'd like to simulate the laminar homogeneous flame propagation, so I set /constant/turbulenceProperties
and set the initial pressure P=101300;
But the temperatures are less than 500K at any time.they're too low.I expect they're around 2000K.
Why?Could you give me some advice?

What is ur initial boundary va

What is ur initial boundary value for the temperature. If the temperature is too low or you have no ignition-source the species will not burn.
So either set the initial value for the internal field to a temperature where you now it will burn e.g
"internalField uniform 2000;"
Or look into diselFoam how to add an ignition source.
PS. I do not do personal support, so please post in the forums.
