This subnode should be used to account for the turbulent mixing caused by the eddy diffusivity in moisture convection, for example when the specified velocity field corresponds to a RANS solution.
The Turbulent Mixing node adds the following contribution to the diffusion coefficient
D of
Equation 7-4 of
Moist Air (MT Interface) node:
where νT is the turbulent kinematic viscosity (SI unit: m
2/s) and
ScT is the turbulent Schmidt number (dimensionless).
Enter a value or expression for the Turbulent kinematic viscosity νT and the
Turbulent Schmidt number ScT. If a turbulent fluid flow interface is active, the
Turbulent kinematic viscosity can be taken directly from this interface.
