The boiling water model template contains domain settings for a simulation modeling the boiling of water. The domain boiling device is specified with two fluids: Water at 100 C and Water Vapour at 100 C. Water at 100 C is the continuous phase and Water Vapour at 100 C is the dispersed phase. The inhomogeneous multiphase model is employed. For details, see The Inhomogeneous (Interfluid Transfer) 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 Thermal Phase Change 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.
