## Multiphase - Phase Change Solvers

Phase Change Solvers In this group, we have included solvers implementing **Phase Change** models to handle cavitation and surface evaporation/condensation (liquid and its vapor phases).

**Phase Change - Cavitation**

- [cavitatingFoam](https://help.sim-flow.com/solvers/cavitating-foam) 2 immiscible fluids, dedicated to cavitation, Homogeneous Equilibrium Model (HEM)
- [interPhaseChangeFoam](https://help.sim-flow.com/solvers/inter-phase-change-foam) 2 immiscible fluids, dedicated to cavitation, VoF, Phase Change Models: Schnerr-Sauer, Merkle, Kunz

- [cavitatingDyMFoam](https://help.sim-flow.com/solvers/cavitating-dym-foam) extension of cavitatingFoam with DyM
- [interPhaseChangeDyMFoam](https://help.sim-flow.com/solvers/inter-phase-change-dym-foam) extension of interPhaseChangeFoam with DyM
- [overInterPhaseChangeDyMFoam](https://help.sim-flow.com/solvers/over-inter-phase-change-dym-foam) extension of interPhaseChangeFoam with Overset, DyM

**Phase Change - Condensation / Evaporation**

- [interCondensatingEvaporatingFoam](https://help.sim-flow.com/solvers/inter-condensating-evaporating-foam) 2 immiscible fluids, phase changes (evaporation and condensation) between a fluid and its vapor phase

- VoF - Volume of Fluid
- DyM - Dynamic Mesh
- Overset - also known as Chimera Grid (Method)

1. 1. All solvers are transient and capable of accommodating buoyancy forces.
2. 2. Additionally, these solvers support:
   - RANS/LES turbulence models
   - Porosity models
   - MRF (except cavitatingFoam and cavitatingDyMFoam)
   - Passive scalar
   - Custom source term (except cavitatingFoam and cavitatingDyMFoam)
