Hello dears.

there is an example for FSD and infinitelyFastChemistry combustion model in openFoam tutorials and I copy that here :

combustionModel infinitelyFastChemistry<psiThermoCombustion,gasHTh ermoPhysics>;
//combustionModel FSD<psiThermoCombustion,gasHThermoPhysics>;

active true;

semiImplicit no;
C 5.0;

Cv 0.1;
ftVarMin 1e-2;

reactionRateFlameArea relaxation;

fuel Methane;

C 2.0;
alpha 1.0;
omega0 0.5;
eta -0.013;
omegaMin 0.01;
sigmaExt 470;
omega0 0.4;
eta -0.00656;
omegaMin 0.01;
sigmaExt 450;

but I can not find any help about the coefficients. can anyone explain them for me?
