Hello foamers,
I would like to find the difinition of alphaEff() wich is used in hEqn.H in following form :

fvm::laplacian(turb.alphaEff(), h)

Does anyone know where "alphaEff()" is defined?

I guess, turb in your message is compressible turbulent model, so for RAS alphaEff is defined as

virtual tmp<volScalarField> alphaEff() const
    return thermo().alphaEff(alphat());
for LES it is

virtual tmp<volScalarField> alphaEff() const
    return thermo().alphaEff(alphaSgs());
and finally thermo.alphaEff() is
