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:
where
= | Ground-normal TKE dissipation rate profile [m^2/s^3] | |
= | Friction velocity [m/s] | |
= | von Kármán constant [-] | |
= | Ground-normal coordinate component [m] | |
= | Aerodynamic roughness length [m] | |
= | Ground-normal displacement height [m] | |
= | Curve-fitting coefficient for YGCJ profiles [-] | |
= | Curve-fitting coefficient for YGCJ profiles [-] |
Required fields:
epsilon | Turbulent kinetic energy dissipation rate [m2/s3]
inlet { // Mandatory entries (unmodifiable) type atmBoundaryLayerInletEpsilon; // Mandatory/Optional (inherited) entries (unmodifiable) ... }
