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.
