forceModel_SchillerNaumannDrag command

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    SchillerNaumannDrag
);
SchillerNaumannDragProps
{
    velFieldName "U";
    voidfractionFieldName "voidfraction";
    interpolation "bool1";
    voidfractionInterpolationType "type1"
    UInterpolationType "type2"
    implForceDEM "bool2";
};
  • U = name of the finite volume fluid velocity field
  • voidfraction = name of the finite volume voidfraction field
  • bool1 = (optional, normally off) flag to use interpolated voidfraction and fluid velocity values
  • type1 = (optional, default cellPoint) interpolation type for voidfraction field
  • type2 = (optional, default cellPointFace) interpolation type for velocity field

bool2 = (optional, normally off) flag to use implicit formulation of drag on DEM side:l

Examples

forceModels
(
    SchillerNaumannDrag
);
SchillerNaumannDragProps
{
    velFieldName "U";
}

Description

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The SchillerNaumannDrag model is a model that calculates the particle based drag force following the correlation of Schiller and Naumann.

Restrictions

none.
