Description🔗
The nutUWallFunction
is boundary condition that provides
a wall function for the turbulent viscosity (i.e. nut
) based on velocity
(i.e. U
) 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 nutUWallFunction;
// Inherited entries
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: nutUWallFunction
|
word | yes | - |
The inherited entries are elaborated in:
- nutWallFunctionFvPatchScalarField.H
- wallFunctionBlenders.H
- Suffers from non-exact restart since
correctNut()
(called throughturbulence->validate
) returns a slightly different value every time it is called. SeenutUSpaldingWallFunctionFvPatchScalarField.C
