forceModel_ShirgaonkarIB command

Syntax:

Defined in couplingProperties dictionary.

forceModels
(
    ShirgaonkarIB
);
ShirgaonkarIBProps
{
    velFieldName "U";
    densityFieldName "density";
    pressureFieldName "pressure";
}; 

• U = name of the finite volume fluid velocity field
• density = name of the finite volume density field
• pressure = name of the finite volume pressure field

Examples:

forceModels
(
    ShirgaonkarIB
);
ShirgaonkarIBProps
{
    velFieldName "U";
    densityFieldName "rho";
    pressureFieldName "p";
} 

Description:

The force model performs the calculation of forces (e.g. fluid-particle interaction forces) acting on each DEM particle. The ShirgaonkarIB model calculates the drag force (viscous and pressure force) acting on each particle in a resolved manner (see Shirgaonkar et al. (2009): "A new mathematical formulation and fast algorithm for fully resolved simulation of self-propulsion", Journal of Comp. Physics). This model is only suited for resolved CFD-DEM simulations where the particle is represented by immersed boundrary method.

Restrictions:

Only for immersed boundary solvers.
