Default kEpsilon.H in twoPhaseEulerFoam

Hi All,

I've looked into the kEpsilon model in the twoPhaseEulerFoam, it seems that the equations are problematic:
fvScalarMatrix kEqn
fvm::ddt(beta, k)
+ fvm::div(phib, k)
- fvm::laplacian
alphak*nuEffb, k,

- fvm::Sp(beta*epsilon/k, k)

in the code, volScalarField G = 2*nutb*(tgradUb() && dev(symm(tgradUb())));
tgradUb = fvc::grad(Ub);

I think the terms in red should include the volumetric fraction "beta", any comments? Thank you,
