momCoupleModel: implicitCouple

Syntax

Defined in couplingProperties dictionary.

momCoupleModels
(
    implicitCouple
);
implicitCoupleProps
{
    velFieldName "U";
    granVelFieldName "Us";
    voidfractionFieldName "voidfraction";
    minAlphaP number;
    KslLimit tuple;
}

velFieldName = (optional, default “U”) name of the finite volume fluid velocity field
granVelFieldName = (optional, default “Us”) name of the finite volume granular velocity field
voidfractionFieldName = (optional, default “voidfraction”) name of the finite volume voidfraction field
minAlphaP = minimum value for local particle volume fraction to calculate the exchange filed (default SMALL)
KslLimit = minimum and maximum value for Ksl field (default min=0, max=1e10)

Examples

implicitCoupleProps
{
    velFieldName "U";
    granVelFieldName "Us";
    voidfractionFieldName "voidfraction";
}

Description

The implicitCouple-model is a momCoupleModel model providing an implicit momentum source term for the CFD solver.

Restrictions

Only for solvers that include implicit momentum exchange.
