Hi all,
I'm a beginners so please forgive me if my questions are dumb...

I'm trying to use fireFoam (v2.2) for multiple reaction combustion. In particular, I'm trying to simulate a diffusion flame with spray injection.
I'm using:

thermoType
{
type hePsiThermo;
mixture reactingMixture;
transport sutherland;
thermo janaf;
energy sensibleEnthalpy;
equationOfState perfectGas;
specie specie;
}

The code runs, but no combustion is started. I'm sure the reactions are correct (they work when using reactingFoam), so I guess the problem is in setting the constant files for combustion. It only works correctly when using only one reaction.

I would like to know if anybody else has tried something similar: do you know how to set the case for multiple reaction?
Do you know if there are any documents/tutorials I can study to understand deeper how fireFoam works?
I've seen dieselFoam was quite similar to what I'm trying to study: do you know if there's something similar in v2.2?

Thank you all!!!

Can we model multiple reactions in reactingFoam ?

Any luck with this?
