MeiLift

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    MeiLift
);
MeiLiftProps
{
    velFieldName         "U";
    useSecondOrderTerms;
    vorticityInterpolationType "type1"
    UInterpolationType   "type2"

    // (optional) forceSubModel switches
    interpolation        switch;
    verbose              switch;
    treatForceExplicit   switch;
    scalarViscosity      switch;
    nu                   scalar;
};

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

  • useSecondOrderTerms = optional keyword for using second order terms in the lift force model. Requires only the keyword, no value.

  • vorticityInterpolationType = interpolation type for vorticity field (default: “cellPoint”)

  • UInterpolationType = interpolation type for velocity field (default: “cellPointFace”)

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

  • scaleDrag

  • scaleDH

  • treatForceExplicit (default: true)

  • verbose

  • interpolation

  • scalarViscosity

Examples

forceModels
(
    MeiLift
);
MeiLiftProps
{
    velFieldName         "U";
    useSecondOrderTerms;
    interpolation        true;
    verbose              true;
}

Description

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The MeiLift model calculates the lift force for each particle based on Loth and Dorgan (2009). In case the keyword “useSecondOrderTerms” is not specified, this lift force model uses the expression of McLaughlin (1991, Journal of Fluid Mechanics 224:261-274).
