The Rotating Machinery, Turbulent Two-Phase Flow, Phase Field Interfaces
The Rotating Machinery, Turbulent Two-Phase Flow, Phase Field multiphysics interfaces () found under the Multiphase Flow > Rotating Machinery, Two-Phase Flow, Phase Field > Turbulent Flow branch (), are multiphysics interfaces designed to track the interface between two immiscible fluids in equipment containing one or more rotating parts. The flow is assumed to be turbulent, that is, to be of high Reynolds number.
When adding a Rotating Machinery Turbulent Two-Phase Flow, Phase Field multiphysics interface, a Turbulent Flow interface and a Phase Field in Fluids interface are added in the Model Builder. A Moving Mesh interface with a Rotating Domain node is added automatically in the Model Builder under the Definitions node. In addition, a multiphysics coupling feature, The Two-Phase Flow, Phase Field Coupling Feature, is automatically added under the Multiphysics node.

Interface Properties
Turbulence Model
By default the Turbulence model type in the settings of the Turbulent Flow interface is set to RANS. A different turbulence model can be selected under Turbulence model.
