solvers::incompressibleMultiphaseVoF: New solver module for multiphase VoF simulations
executed with foamRun for single region simulations of foamMultiRun for
multi-region simulations. Replaces multiphaseInterFoam and all the
corresponding tutorials have been updated and moved to
tutorials/modules/incompressibleMultiphaseVoF.
incompressibleMultiphaseVoF is derived from the multiphaseVoFSolver which adds
multiphase capability to the VoFSolver base-class used as the basis of all
two-phase and multiphase VoF solvers.
Class
Foam::solvers::incompressibleMultiphaseVoF
Description
Solver module for the solution of multiple incompressible, 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.

The momentum and other fluid properties are of the "mixture" and a single

Either mixture or two-phase transport modelling may be selected. In the

Description
|
||||
Solver module for the solution of multiple incompressible, 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::incompressibleMultiphaseVoFMixture
|
||||
|
||||
Description
|
||||
Incompressible multiphase mixture for interface-capturing simulations.
|
||||
|
||||
Derived from viscosity so that it can be used in conjunction with the
|
||||
incompressible turbulence models.
|
||||
|
||||
Surface tension and contact-angle is handled for the interface between each
|
||||
phase-pair.

Class
|

Foam::incompressibleMultiphaseMixture
|
||||
Foam::multiphaseVoFMixture
|
||||
|
||||
Description
|
||||
Incompressible multiphase mixture with built in solution for the
|
||||
phase fractions with interface compression for interface-capturing.
|
||||
|
||||
Derived from viscosity so that it can be used in conjunction
|
||||
with the incompressible turbulence models.
|
||||
Multiphase VoF mixture with support for interface properties
|
||||
|
||||
Surface tension and contact-angle is handled for the interface
|
||||
between each phase-pair.

Class
|
||||
Foam::solvers::multiphaseVoFSolver
|
||||
|
||||
Description
|
||||
Base solver module for the solution of multiple 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.
|
||||
|
||||
Uses the flexible PIMPLE (PISO-SIMPLE) solution for time-resolved and
|
||||
pseudo-transient and steady simulations.
