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:

where

	=	turblence thermal diffusivity
	=	turblence viscosity
	=	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
    }
