The Turbulent Two-Phase Flow, Level Set Interfaces
The Turbulent Two-Phase Flow, Level Set interfaces () found under the Multiphase Flow>Two-Phase Flow, Level Set branch (), are multiphysics interfaces designed to track the interface between two immiscible fluids. The flow is assumed to be turbulent, that is, to be of high Reynolds number. The fluids can be incompressible or compressible.
When adding a Turbulent Two-Phase Flow, Level Set multiphysics interface, a Turbulent Flow interface and a Level Set interface are added in the Model Builder. In addition, a multiphysics coupling feature, The Two-Phase Flow, Level Set Coupling Feature, is automatically added under the Multiphysics node. Another multiphysics coupling feature, The Wetted Wall Coupling Feature, can be added when needed.

Turbulence Model
By default the Turbulence model type selected is RANS. Turbulent flow can be simulated by changing the Turbulence model type to RANS.
