An additional layer has been added into the phase system hierarchy which facilitates the application of phase transfer modelling. These are models which exchange mass between phases without the thermal coupling that would be required to represent phase change. They can be thought of as representation changes; e.g., between two phases representing different droplet sizes of the same physical fluid. To facilitate this, the heat transfer phase systems have been modified and renamed and now both support mass transfer. The two sided version is only required for derivations which support phase change. The following changes to case settings have been made: - The simplest instantiated phase systems have been renamed to basicTwoPhaseSystem and basicMultiphaseSystem. The heatAndMomentumTransfer*System entries in constant/phaseProperties files will need updating accordingly. - A phaseTransfer sub-model entry will be required in the constant/phaseProperties file. This can be an empty list. - The massTransfer switch in thermal phase change cases has been renamed phaseTransfer, so as not to be confused with the mass transfer models used by interface composition cases. This work was supported by Georg Skillas and Zhen Li, at Evonik

Class
|
|
Foam::MassTransferTransferPhaseSystem
|
|
|
|
Description
|
|
Class which models non-thermally-coupled mass transfers; i.e.,
|
|
representation changes, rather than phase changes.
