Sig Phase Change

The Special Interest Group on Phase Change was initiated at the 10th OpenFOAM Workshop in Ann Arbor. This article has the objective of documenting both theoretical aspects and OpenFOAM implementations of phase change models. Please feel free to contribute.

4.1 Solvers

4.1.1 interPhaseChangeFoam

Valid versions:

• Description: 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. The momentum and other fluid properties are of the "mixture" and a single momentum equation is solved. The set of phase-change models provided are designed to simulate cavitation but other mechanisms of phase-change are supported within this solver framework.

• Code: OF2.3.x, OF2.4.x

4.1.2 interPhaseChangeDyMFoam

Valid versions:

• Description: 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. The momentum and other fluid properties are of the "mixture" and a single momentum equation is solved. The set of phase-change models provided are designed to simulate cavitation but other mechanisms of phase-change are supported within this solver framework.

• Code: OF2.3.x, OF2.4.x

4.1.3 cavitatingFoam

Valid versions:

• Description: Transient cavitation code based on the homogeneous equilibrium model from which the compressibility of the liquid/vapour "mixture" is obtained.

• Code: OF2.3.x, OF2.4.x

4.1.4 cavitatingDyMFoam

Valid versions:

• Description: Transient cavitation code based on the homogeneous equilibrium model from which the compressibility of the liquid/vapour "mixture" is obtained.

• Code: OF2.3.x, OF2.4.x
