How to understand "Y[inertIndex] = scalar(1) - Yt" in YEqn.H
As we can see the following codes in YEqn.H:
label inertIndex = -1;
if (Y[i].name() != inertSpecie)
volScalarField& Yi = Y[i];
+ mvConvection->fvmDiv(phi, Yi)
- fvm::laplacian(turbulence->muEff(), Yi)
Yt += Yi;
inertIndex = i;
Y[inertIndex] = scalar(1) - Yt;
What does the "Y[inertIndex]"meas?How can I understand it?and what does the "Y[inertIndex]"use?
Thanks in advance!
It is mass fraction of the inert species.
For example the N2 mass fraction in the following:
CH4+2(O2+3.76N2) --> CO2+2H2O+7.52N2
Thanks Moslem,I think you are right!
