Class
    Foam::inhomogeneousEGRMixture
 
Description
    Combustion mixture for inhomogeneous lean, stoichiometric or rich conditions
    with exhaust gas recirculation
 
    in which the mixture-fraction \c ft, fuel mass-fraction \c fu and exhaust
    gas recirculation mass-fraction \c egr define the composition.
