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
