Applies sources on k and either epsilon or omega to prevent them droping below a specified ambient value for atmospheric boundary layer modelling. Such adjustment reportedly increases numerical stability for very stable atmospheric stability conditions, and prevents nonphysical oscillations in regions of low shear at higher altitudes. More...

Detailed Description

Applies sources on k and either epsilon or omega to prevent them droping below a specified ambient value for atmospheric boundary layer modelling. Such adjustment reportedly increases numerical stability for very stable atmospheric stability conditions, and prevents nonphysical oscillations in regions of low shear at higher altitudes.

Corrections applied to:

  k         | Turbulent kinetic energy                  [m2/s2]

Corrections applied to either of the below, if exist:

  epsilon   | Turbulent kinetic energy dissipation rate [m2/s3]
  omega     | Specific dissipation rate                 [1/s]

Required fields:

  k             | Turbulent kinetic energy                    [m2/s2]
  epsilon/omega | Dissipation rate OR Spec. dissipation rate  [m2/s3]/[1/s]

Usage
Example by using constant/fvOptions:
atmAmbientTurbSource1
{
    // Mandatory entries (unmodifiable)
    type                  atmAmbientTurbSource;

    atmAmbientTurbSourceCoeffs
    {
        // Mandatory (inherited) entries (unmodifiable)
        selectionMode    all;

        // Mandatory entries (unmodifiable)
        kAmb              0.0;

        // Optional entries (unmodifiable)
        rho               rho;
        epsilonAmb        0.0;
        omegaAmb          0.0;
    }

    // Optional (inherited) entries
    ...
}

where the entries mean:

Property Description Type Req'd Dflt
type Type name: atmAmbientTurbSource word yes -
kAmb Ambient value for k scalar yes -
rho Name of density field word no rho
epsilonAmb Ambient value for epsilon scalar no 0.0
omegaAmb Ambient value for omega scalar no 0.0
