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; infinitelyFastChemistryCoeffs { semiImplicit no; C 5.0; } FSDCoeffs { Cv 0.1; ftVarMin 1e-2; reactionRateFlameArea relaxation; fuel Methane; relaxationCoeffs { C 2.0; alpha 1.0; Methane { omega0 0.5; eta -0.013; omegaMin 0.01; sigmaExt 470; } Propane { 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? thanks. Asadi. |
