Description🔗
The atmBoundaryLayerInletK
is a boundary condition that provides
boundary condition for the turbulent kinetic energy (i.e. k
)
for homogeneous, two-dimensional, dry-air, equilibrium and neutral
atmospheric boundary layer modelling.
The ground-normal k
profile expression:
where:
Property | Description |
---|---|
\(k\) | Ground-normal turbulent kinetic energy profile [m^2/s^3] |
\(u^*\) | Friction velocity [m/s] |
\(C_\mu\) | Empirical model constant [-] |
\(C_1\) | Curve-fitting coefficient for YGCJ profiles [-] |
\(C_2\) | Curve-fitting coefficient for YGCJ profiles [-] |
Usage🔗
The condition requires entries in both the boundary and field files.
