## 37.2. Cavitating Water

The cavitation model template contains domain settings and fluid models for a cavitating flow. The domain `cavitating device` is specified with two fluids, `Water at 25 C` and `Water Vapour at 25 C`. The homogeneous multiphase model is employed. The Homogeneous Model in the CFX-Solver Modeling Guide.

The `Rayleigh Plesset` model is used to model cavitation in the domain. For details, see Rayleigh Plesset Model in the CFX-Solver Modeling Guide.

Boiling is modeled by setting the Mass Transfer option on the Fluid Pair Models tab to `Phase Change` (which uses the Thermal Phase Change model and requires a saturation temperature).

Review all settings applied to the simulation and create suitable boundary conditions. For details, see Cavitation Model in the CFX-Solver Modeling Guide. Initialization data must also be set; for details, see Initial Conditions for a Multiphase Simulation in the CFX-Solver Modeling Guide.
