solvers::compressibleMultiphaseVoF: New solver module for compressible multiphase VoF simulations
executed with foamRun for single region simulations of foamMultiRun for
multi-region simulations. Replaces compressibleMultiphaseInterFoam and all the
corresponding tutorials have been updated and moved to
tutorials/modules/compressibleMultiphaseVoF.
compressibleMultiphaseVoF is derived from the multiphaseVoFSolver which adds
compressible multiphase capability to the VoFSolver base-class used as the basis
of all two-phase and multiphase VoF solvers.
Class
Foam::solvers::compressibleMultiphaseVoF
Description
Solver module for the solution of multiple compressible, isothermal
immiscible fluids using a VOF (volume of fluid) phase-fraction based
interface capturing approach, with optional mesh motion and mesh topology
changes including adaptive re-meshing.
The momentum and other fluid properties are of the "mixture" and a single
momentum equation is solved.
A mixture approach for momentum transport is provided in which a single
laminar, RAS or LES model is selected to model the momentum stress.
Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
pseudo-transient and steady simulations.

Description
|
||||
Solver module for the solution of multiple compressible, isothermal
|
||||
immiscible fluids using a VOF (volume of fluid) phase-fraction based
|
||||
interface capturing approach, with optional mesh motion and mesh topology
|
||||
changes including adaptive re-meshing.
|
||||
|
||||
The momentum and other fluid properties are of the "mixture" and a single
|
||||
momentum equation is solved.
|
||||
|
||||
A mixture approach for momentum transport is provided in which a single
|
||||
laminar, RAS or LES model is selected to model the momentum stress.
|
||||
|
||||
Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
|
||||
pseudo-transient and steady simulations.

Foam::compressibleMultiphaseVoFMixture
|

|

Description
|
||||
Compressible multiphase mixture for interface-capturing simulations.
|
||||
|
||||
Derived from viscosity so that it can be used in conjunction with the
|
||||
compressible turbulence models.
|
||||
|
||||
Surface tension and contact-angle is handled for the interface between each
|
||||
phase-pair.

|

Description
|
||||
Solver for n compressible, non-isothermal immiscible fluids using a VOF
|
||||
(volume of fluid) phase-fraction based interface capturing approach.
|
||||
|
||||
The momentum and other fluid properties are of the "mixture" and a single
|
||||
momentum equation is solved.
|
||||
|
||||
Turbulence modelling is generic, i.e. laminar, RAS or LES may be selected.
