Turbulent Prandtl Number for Enthalpy:

The turbulent Prandtl number for enthalpy transport can be controlled by means of the TURBULENT FLUX CLOSURE singleton located under HEAT TRANSFER MODEL:
FLOW:

DOMAIN:

FLUID MODELS:
HEAT TRANSFER MODEL:
Option =
TURBULENT FLUX CLOSURE:
Option = Eddy Diffusivity
Turbulent Prandtl Number = <real> # default=0.9
