Class
|
|
Foam::MovingPhaseModel
|
|
|
|
Description
|
|
Class which represents a moving fluid phase. Holds the velocity, fluxes and
|
|
turbulence model and can generate the momentum equation. The interface is
|
|
quite restrictive as it also has to support an equivalent stationary model,
|
|
which does not store motion fields or a turbulence model.
|
|
|
|
Possible future extensions include separating the turbulent functionality
|
|
into another layer.
