Class
Foam::MovingPhaseModel
Description
Class which represents a moving fluid phase. Holds the velocity, fluxes and
turbulence model. Provides access to the turbulent quantities.
Possible future extensions include separating the turbulent fuctionality
into another layer. It should also be possible to replace this layer with a
stationary phase model, in order to model packed beds or simple porous
media. This would probably require extra functionality, such as returning
the inputs into the general pressure equation (A, HbyA, etc ...).
Note that this class does not return the turbulence model, it just provides
indirect access to the turbulent data. This is so a layer without
turbulence modelling (such as a stationary model) could be substituted.
