forceModel_ShirgaonkarIB command¶
Syntax¶
Defined in couplingProperties dictionary.
forceModels
(
ShirgaonkarIB
);
ShirgaonkarIBProps
{
velFieldName "U";
pressureFieldName "p";
twoDimensional;
depth scalar1;
verbose switch1;
treatForceExplicit switch2;
};
- U = name of the finite volume fluid velocity field
- p = name of the finite volume pressure field
- twoDimensional = optional keyword for conducting a two dimensional calculation
- scalar1 = optional, only necessary if twoDimensional is active
- switch1 = (optional, default false) sub model switch, see forceSubModel for details
- switch2 = (optional, default false) sub model switch, see forceSubModel for details
Examples¶
forceModels
(
ShirgaonkarIB
);
ShirgaonkarIBProps
{
velFieldName "U";
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 boundary method.

Restrictions¶
Only for immersed boundary solvers.
