forceModel_KochHillDrag command

Syntax:

Defined in couplingProperties dictionary.

forceModels
(
    KochHillDrag
);
KochHillDragProps
{
    velFieldName "U";
    voidfractionFieldName "voidfraction"; 
    interpolation "bool1";
    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 bool2 = (optional, normally off) flag to use implicit formulation of drag on DEM side:l

Examples:

forceModels
(
    KochHillDrag
);
KochHillDragProps
{
    velFieldName "U";
    voidfractionFieldName "voidfraction"; 
} 

Description:

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The KochHillDrag model is a model that calculates the particle based drag force following the correlation of Koch & Hill (2001) (see van Buijtenen et al. (2011): "Numerical and experimental study on multiple-spout fluidized beds", ChemEngScience).

Restrictions:

none.
