Detailed Description

This boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, based on velocity, i.e. U, for low- and high-Reynolds number turbulence models.

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries (unmodifiable)
    type            nutUWallFunction;

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Req'd	Dflt
type	Type name: nutUWallFunction	word	yes	-

The inherited entries are elaborated in:

• nutWallFunctionFvPatchScalarField.H

Note

• Suffers from non-exact restart since correctNut() (called through turbulence->validate) returns a slightly different value every time it is called. See nutUSpaldingWallFunctionFvPatchScalarField.C.
• See nutWallFunctionFvPatchScalarField.H for the wall function blending treatments.
