forceModel_DiFeliceDrag command

Syntax:

Defined in couplingProperties dictionary.

forceModels
(
    DiFeliceDrag
);
DiFeliceDragProps
{
    velFieldName "U";
    densityFieldName "density";
    interpolation;
}; 

• U = name of the finite volume fluid velocity field
• density = name of the finite volume gravity field
• interpolation = flag to use interpolated voidfraction and velocity values (normally off)

Examples:

forceModels
(
    DiFeliceDrag
);
DiFeliceDragProps
{
    velFieldName "U";
    densityFieldName "rho";
    interpolation;
} 

Description:

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The DiFeliceDrag model is a model that calculates the particle based drag force following the correlation of Di Felice (see Zhou et al. (2010), JFM).

Restrictions:

none.
