This boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, based on velocity, i.e. U, for atmospheric boundary layer modelling. It is designed to be used in conjunction with the atmBoundaryLayerInletVelocity boundary condition.

This boundary condition provides a wall constraint on the turbulent viscosity, i.e. nut, based on velocity, i.e. U, for atmospheric boundary layer modelling. It is designed to be used in conjunction with the atmBoundaryLayerInletVelocity boundary condition.
The governing equation of the boundary condition:
\[ \u = \frac{\u^*}{\kappa} ln \left(\frac{z + z_0}{z_0}\right) \]
where
| \( \u^* \) | = | Friction velocity |
| \( \kappa \) | = | von Kármán constant |
| \( z_0 \) | = | Surface roughness length [m] |
| \( z \) | = | Ground-normal coordinate |
Required fields:
nut | Turbulent viscosity [m2/s]
U | Velocity [m/s]<patchName>
{
// Mandatory entries (unmodifiable)
type atmNutUWallFunction;
// Mandatory entries (runtime modifiable)
z0 uniform 0.001;
// Optional entries (unmodifiable)
boundNut true;
// Optional (inherited) entries
...
}
where the entries mean:
| Property | Description | Type | Req'd | Dflt |
|---|---|---|---|---|
type | Type name: atmNutUWallFunction | word | yes | - |
z0 | Surface roughness length [m] | PatchFunction1<scalar> | yes | - |
boundNut | Flag: zero-bound nut near wall | bool | no | true |
