Description🔗

The nutkWallFunction is boundary condition that provides a wall function for the turbulent viscosity (i.e. nut) based on the turbulent kinetic energy, (i.e. k) for for low- and high-Reynolds number applications.

Usage🔗

The condition requires entries in both the boundary and field files.

Boundary file🔗

<patchName>
{
    type            wall;
    ...
}

Field file🔗

<patchName>
{
    // Mandatory entries
    type            nutkWallFunction;

    // Inherited entries
    ...
}

where:

The inherited entries are elaborated in:

• nutWallFunctionFvPatchScalarField.H
• wallFunctionBlenders.H
