Detailed Description

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]
Usage
Example of the boundary condition specification:
<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 Reqd 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

The inherited entries are elaborated in:
