Detailed Description

This boundary condition provides a log-law type ground-normal inlet boundary condition for the turbulent kinetic energy dissipation rate (i.e. epsilon) for homogeneous, two-dimensional, dry-air, equilibrium and neutral atmospheric boundary layer modelling.

The ground-normal epsilon profile expression:

\[ \epsilon = \frac{(u^*)^3}{\kappa (z - d + z_0)} \sqrt{C_1 \ln \left( \frac{z - d + z_0}{z_0} \right) + C_2} \]

where

\( \epsilon \) = Ground-normal TKE dissipation rate profile [m^2/s^3]
\( u^* \) = Friction velocity [m/s]
\( \kappa \) = von Kármán constant [-]
\( z \) = Ground-normal coordinate component [m]
\( z_0 \) = Aerodynamic roughness length [m]
\( d \) = Ground-normal displacement height [m]
\( C_1 \) = Curve-fitting coefficient for YGCJ profiles [-]
\( C_2 \) = Curve-fitting coefficient for YGCJ profiles [-]

Required fields:

        epsilon   | Turbulent kinetic energy dissipation rate   [m2/s3]
