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.

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]
