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.

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 [-] |

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