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 for rough walls.

Usage

Example of the boundary condition specification:

<patchName>
{
    // Mandatory entries (unmodifiable)
    type                nutURoughWallFunction;
    roughnessHeight     1e-5;
    roughnessConstant   0.5;
    roughnessFactor     1;

    // Optional entries (unmodifiable)
    maxIter             10;
    tolerance           0.0001;

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property	Description	Type	Req'd	Dflt
`type`	Type name: nutURoughWallFunction	word	yes	-
`roughnessHeight`	Roughness height	scalar	yes	-
`roughnessConstant`	Roughness constant	scalar	yes	-
`roughnessFactor`	Scaling factor	scalar	yes	-
`maxIter`	Number of Newton-Raphson iterations	label	no	10
`tolerance`	Convergence tolerance	scalar	no	0.0001

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.
