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]
Usage
Example of the boundary condition specification: 
inlet
{
    // Mandatory entries (unmodifiable)
    type            atmBoundaryLayerInletEpsilon;

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

where the entries mean:
