Phase turbulence stabilisation.
In the limit of a phase-fraction->0 the turbulence properties cannot be obtained from the phase turbulence model, coupling to the other phase/phases is required. The phaseTurbulenceStabilisation fvModel stabilises the phase turbulence properties by adding transfer terms from the corresponding properties of the other phases when the phase-fraction is less than the specified alphaInversion
. This implementation is a generalisation of the approach used in the Foam::RASModels::LaheyKEpsilon and Foam::RASModels::continuousGasKEpsilon models to handle phase-inversion and free-surface flow and can be used with any combination of RAS turbulence models.
To stabilise the solution of the phase turbulence equations alphaInversion
can be set to a small value e.g. 1e-2, but unless the phase turbulence model is specifically designed to handle phase-inversion and both continuous and dispersed regimes it may be useful to set alphaInversion
to a higher value, corresponding to the phase-fraction at which transition from continuous to dispersed happens and effectively use the turbulence properties of the other phase when the phase is dispersed. This is of course an approximation to the real system and if accurate handling of both the continuous and dispersed phase regimes is required specially developed models should be used.
