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$=Turbulence thermal diffusivity
$ \mu_t $=Turbulence viscosity
$ Pr_t $=Turbulent Prandtl number
Usage
Example of the boundary condition specification: 
<patchName>
{
    // Mandatory entries
    type            alphatWallFunction;

    // Optional entries
    Prt             <scalar>;

    // Inherited entries
    ...
}

where the entries mean:

Property Description Type Reqd Deflt
type Type name: alphatWallFunction word yes -
Prt Turbulent Prandtl number scalar no 0.85
