    Applies corrections to turbulence kinetic energy equation and turbulence
    viscosity field for incompressible multiphase flow cases.
    
    Turbulence kinetic energy is over-predicted in VOF solvers at the phase
    interface and throughout the water column in nearly-potential flow regions
    beneath surface waves.
    
    This fvOption applies corrections based on the references:
    
        Buoyancy source term in turbulence kinetic energy equation:
    
            Devolder, B., Rauwoens, P., and Troch, P. (2017).
            Application of a buoyancy-modified k-w SST turbulence model to
            simulate wave run-up around a monopile subjected to regular waves
            using OpenFOAM.
            Coastal Engineering, 125, 81-94.
    
        Correction to turbulence viscosity field:
    
            Larsen, B.E. and Fuhrman, D.R. (2018).

            Reynolds-averaged Navier-Stokes models

    Example usage:
    
        multiphaseStabilizedTurbulence1
        {
            type            multiphaseStabilizedTurbulence;
            active          yes;
    
            multiphaseStabilizedTurbulenceCoeffs
            {
                // Optional coefficients
                lambda2         0.1;   // A value of 0 sets the nut correction to 0
                Cmu             0.09;  // from k-epsilon model
                C               1.51;  // model coefficient from k-omega model
                alpha           1.36;  // 1/Prt
            }
        }
    
    Thanks go to the Turbulence Technical Committee, and the useful discussions
    with and code testing by Bjarke Eltard-Larsen and David Fuhrman (Technical
    University of Denmark).
