OpenFOAM includes the following solvers for multiphase flows:

cavitatingFoam

Transient cavitation code based on the homogeneous equilibrium model from which the compressibility of the liquid/vapour “mixture” is obtained.

cavitatingDyMFoam

Transient cavitation code based on the homogeneous equilibrium model from which the compressibility of the liquid/vapour “mixture” is obtained.

compressibleInterFoam

Solver for 2 compressible, non-isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach.

compressibleInterDyMFoam

Solver for 2 compressible, non-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.

compressibleMultiphaseInterFoam

Solver for n compressible, non-isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach.

driftFluxFoam

Solver for 2 incompressible fluids using the mixture approach with the drift-flux approximation for relative motion of the phases.

interFoam

Solver for 2 incompressible, isothermal immiscible fluids using a VOF (volume of fluid) phase-fraction based interface capturing approach.

interDyMFoam

Solver for 2 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.

interMixingFoam

Solver for 3 incompressible fluids, two of which are miscible, using a VOF method to capture the interface.

interPhaseChangeFoam

Solver for 2 incompressible, isothermal immiscible fluids with phase-change (e.g. cavitation). Uses a VOF (volume of fluid) phase-fraction based interface capturing approach.

interPhaseChangeDyMFoam

Solver for 2 incompressible, isothermal immiscible fluids with phase-change (e.g. cavitation). Uses a VOF (volume of fluid) phase-fraction based interface capturing approach, with optional mesh motion and mesh topology changes including adaptive re-meshing.

multiphaseEulerFoam

Solver for a system of many compressible fluid phases including heat-transfer.

multiphaseInterFoam

Solver for n incompressible fluids which captures the interfaces and includes surface-tension and contact-angle effects for each phase.

multiphaseInterDyMFoam

Solver for n incompressible fluids which captures the interfaces and includes surface-tension and contact-angle effects for each phase.

potentialFreeSurfaceFoam

Incompressible Navier-Stokes solver with inclusion of a wave height field to enable single-phase free-surface approximations

potentialFreeSurfaceDyMFoam

Incompressible Navier-Stokes solver with inclusion of a wave height field to enable single-phase free-surface approximations.

reactingMultiphaseEulerFoam

Solver for a system of any number of compressible fluid phases with a common pressure, but otherwise separate properties. The type of phase model is run time selectable and can optionally represent multiple species and in-phase reactions. The phase system is also run time selectable and can optionally represent different types of momentun, heat and mass transfer.

reactingTwoPhaseEulerFoam

Solver for a system of 2 compressible fluid phases with a common pressure, but otherwise separate properties. The type of phase model is run time selectable and can optionally represent multiple species and in-phase reactions. The phase system is also run time selectable and can optionally represent different types of momentun, heat and mass transfer.

twoLiquidMixingFoam

Solver for mixing 2 incompressible fluids.

twoPhaseEulerFoam

Solver for a system of 2 compressible fluid phases with one phase dispersed, e.g. gas bubbles in a liquid including heat-transfer.

In this tutorial, you will learn how to simulate a multiphase case (lockExchange tutorial) from OpenFOAM.
