Description🔗
The epsilonWallFunction
is boundary condition that provides
wall functions for the turbulent kinetic energy dissipation rate
(i.e. epsilon
) and the turbulent kinetic energy production contribution
(i.e. G
) for low- and high-Reynolds number simulations.
Usage🔗
The condition requires entries in both the boundary and field files.
Boundary file🔗
<patchName>
{
type wall;
...
}
Field file🔗
<patchName>
{
// Mandatory entries
type epsilonWallFunction;
// Optional entries
lowReCorrection <bool>;
// Inherited entries
...
}
where:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type |
Type name: epsilonWallFunction
|
word | yes | - |
lowReCorrection |
Flag: apply low-Re correction | bool | no | false |
The inherited entries are elaborated in:
- wallFunctionCoefficients.H
- wallFunctionBlenders.H
