Description🔗
The nutUTabulatedWallFunction
is boundary condition that provides
a wall constraint on the turbulent viscosity (i.e. nut
) based on velocity
(i.e. U
), for low- and high-Reynolds number applications.
As input, the user specifies a look-up table of u+
as a function of
near-wall Reynolds number.
The table should be located in the $FOAM_CASE/constant
directory.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type wall;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type nutUTabulatedWallFunction;
uPlusTable <word>;
// Inherited entries
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: nutUTabulatedWallFunction
|
word | yes | - |
uPlusTable |
u+ as a function of Re table name | word | yes | - |
The inherited entries are elaborated in:
- nutWallFunctionFvPatchScalarField.H
-
uniformInterpolationTable.H
- The tables are not registered since the same table object may be used for more than one patch.
