1) PhaseIncompressibleTurbulenceModel class was changed to use
uniform alpha and non-uniform rho templates. This fits the need
of incompressible two phase turbulence models.
2) A new type DPMIncompressibleTurbulenceModel was created for
non-uniform alpha and uniform rho. It is used in single phase flows
in DPM solvers where alpha represents the volumen occupancy.
3) A new type incompressibleRhoTurbulenceModel was created where
non-uniform rho is allowed.
4) A new base templated turbulent class for two-phase VOF named
VoFphaseTurbulentTransportModel was implemented which is created
templating on PhaseIncompressibleTurbulenceModel and
incompressibleRhoTurbulenceModel
5) In order to make the chnage to rho based VOF turbulence a help
class was added incompressibleInterPhaseTransportModel templated
on the mixing.
fvOptions does not have the appropriate structure to support MRF as it
is based on option selection by user-specified fields whereas MRF MUST
be applied to all velocity fields in the particular solver. A
consequence of the particular design choices in fvOptions made it
difficult to support MRF for multiphase and it is easier to support
frame-related and field related options separately.
Currently the MRF functionality provided supports only rotations but
the structure will be generalized to support other frame motions
including linear acceleration, SRF rotation and 6DoF which will be
run-time selectable.
