turbulenceSlipInduced

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    turbulenceSlipInduced
);

turbulenceSlipInducedProps
{
    velFieldName     "U";
    Cmu              scalar;
    maxSource        scalar;
    suppressProbe    switch;
    verbose          switch;
    interpolation    switch;
    UinterpolationType "type1";
};

  • velFieldName = name of the finite volume velocity field (default: “U”)

  • Cmu = coefficient for calculation of contribution to turbulent viscosity

  • maxSource = (optional) limit maximal turbulence

  • suppressProbe = can be used to suppress the output of the probe model (default: false)

  • UinterpolationType = interpolation type for U field (default: “cellPointFace”)

This forceModel reads the following forceSubModel switches and overwrites the defaults as indicated in parentheses:

  • verbose

  • interpolation

Examples

forceModels
(
    turbulenceSlipInduced
);

turbulenceSlipInducedProps
{
    velFieldName "U";
    Cmu 0.09;
}

Description

This forceModel accounts for additional turbulence production due to particles. The additional amount of turbulent viscosity added in the momentum equations is calculated as \frac{C_\mu}{V_\mathrm{cell}} \sum_\mathrm{p\ in\ cell} V_\mathrm{part} d_\mathrm{part} \left| U_\mathrm{rel} \right|

Restrictions

None.
