Detailed Description

This boundary condition provides a log-law type ground-normal inlet boundary condition for the streamwise component of wind velocity (i.e. u) for homogeneous, two-dimensional, dry-air, equilibrium and neutral atmospheric boundary layer modelling.

The ground-normal streamwise flow speed profile expression:

\[ u = \frac{u^*}{\kappa} \ln \left( \frac{z - d + z_0}{z_0} \right) \]

\[ v = w = 0 \]

where

\( u \)	=	Ground-normal streamwise flow speed profile [m/s]
\( v \)	=	Spanwise flow speed [m/s]
\( w \)	=	Ground-normal flow speed [m/s]
\( u^* \)	=	Friction velocity [m/s]
\( \kappa \)	=	von Kármán constant [-]
\( z \)	=	Ground-normal coordinate component [m]
\( d \)	=	Ground-normal displacement height [m]
\( z_0 \)	=	Aerodynamic roughness length [m]

Required fields:

        U   | Velocity                                          [m/s]

Usage

Example of the boundary condition specification:

inlet
{
    // Mandatory entries (unmodifiable)
    type            atmBoundaryLayerInletVelocity;

    // Mandatory/Optional (inherited) entries (unmodifiable)
    ...
}

where the entries mean:
