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.
