This is done by editing the CCL. The following options are available for the heat transfer model:

constant turbulent heat fluxes
FLOW:
DOMAIN: Domain 1
FLUID MODELS:
HEAT TRANSFER MODEL:
Option = Thermal Energy
TURBULENT FLUX CLOSURE:
Option = User Defined
uh = 1. [m^3 s^-3]
vh = 2. [m^3 s^-3]
wh = 3. [m^3 s^-3]
END
END
END
END
END

Transport equation for turbulent heat fluxes:
FLOW:
DOMAIN: Domain 1
FLUID MODELS:
HEAT TRANSFER MODEL:
Option = Thermal Energy
TURBULENT FLUX CLOSURE:
Option = Transport Equation
END
END
END
END
END

No boundary values can be set. Inlet values are by default at zero.
