nutLowReWallFunction
boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut
, for low Reynolds number models.nut
to zero, and provides an access function to calculate \(y^+\).nutLowReWallFunction
condition inherits the traits of the nutWallFunction boundary condition.Required fields:
nut | Turbulent viscosity [m2/s]
The model expressions:
\[ \nu_t = 0 \]
where
\( \nu_t \) | = | Turbulent viscosity [m2/s] |
Example of the boundary condition specification:
<patchName> { // Mandatory entries (unmodifiable) type nutLowReWallFunction; // Optional (inherited) entries ... }
where the entries mean:
Property | Description | Type | Required | Default |
---|---|---|---|---|
type | Type name: nutLowReWallFunction | word | yes | - |
