Detailed Description

template<class BasicTurbulenceModel>
class Foam::RASModels::mixtureKEpsilon< BasicTurbulenceModel >

Mixture k-epsilon turbulence model for two-phase gas-liquid systems.

The basic structure of the model is based on: 

    Behzadi, A., Issa, R. I., & Rusche, H. (2004).
    Modelling of dispersed bubble and droplet flow at high phase fractions.
    Chemical Engineering Science, 59(4), 759-770.

but an effective density for the gas is used in the averaging and an alternative model for bubble-generated turbulence from: 

    Lahey Jr, R. T. (2005).
    The simulation of multidimensional multiphase flows.
    Nuclear Engineering and Design, 235(10), 1043-1060.

The default model coefficients are 

    mixtureKEpsilonCoeffs
    {
        Cmu         0.09;
        C1          1.44;
        C2          1.92;
        C3          C2;
        sigmak      1.0;
        sigmaEps    1.3;
