Detailed Description

This boundary condition provides a turbulent thermal diffusivity condition when using wall functions.

- replicates OpenFOAM v1.5 (and earlier) behaviour

The turbulent thermal diffusivity calculated using:

\[ \alpha_t = \frac{\mu_t}{Pr_t} \]

where

\( \alpha_t\) = turblence thermal diffusivity
\( \mu_t \) = turblence viscosity
\( Pr_t \) = turblent Prandtl number
Usage
Property Description Required Default value
nut turbulence viscosity field name no nut
Prt turbulent Prandtl number no 0.85

Example of the boundary condition specification: 

    <patchName>
    {
        type            alphatWallFunction;
        nut             nut;
        Prt             0.85;
        value           uniform 0; // optional value entry
    }
