The Turbulent Mixing subnode is available from the context menu (right-click the
Transport Properties parent node) or from the
Physics toolbar,
Attributes menu. The node defines the turbulent kinematic viscosity using a turbulent Schmidt number.
This feature is available if Convection is selected as a transport mechanism and if the
Diffusion model is
Mixture-averaged or
Fick’s law.
Some physics interfaces provide the turbulent kinematic viscosity, and these appear as options in the Turbulent kinematic viscosity νT (SI unit: m
2/s) list. The list always contains the
User defined option that makes it possible to enter any value or expression.
