fireFoam+DES+PaSR Cann't ignite
 
Dear Foamers,

I'm trying to use fireFoam + DES+ PaSR to simulate the flow and combustion inside the channel, that is,of course, the interaction between vortex and flame front.

And,now the biggest problem is that I can run both fireFoam + LES + PaSR and reactingFoam + DES + PaSR. But fireFoam + DES + PaSR can't ignite normally.

To be exact, I have tried various ignition method of setfields and fvOptions for several days, but they have not been successful.

At present, it is normal for fireFoam + LES + PaSR to simulate cold flow (pure flow without ignition and combustion).

So, to sum up, my question is: is fireFoam + DES+ PaSR feasible?

Thank you for your attention.

Can't ignite
 
I evenly set the inlet temperature to 2000K, but there is still no chemical reaction, that is to say, the ignition is still not successful.:mad:

Any help and Suggestion?

Thank you all.
