forceModel ShirgaonkarIB command

Syntax

Defined in couplingProperties dictionary.

forceModels
(
    ShirgaonkarIB
);
ShirgaonkarIBProps
{
    velFieldName      "U";
    pressureFieldName "pressure";
    twoDimensional;
    useTorque;
    treatForceExplicit switch1;
}

  • U = name of the finite volume fluid velocity field

  • pressure = name of the finite volume pressure field

  • twoDimensional = optional keyword for conducting a two dimensional calculation

  • useTorque = optional keyword for calculating particle torque

  • switch1 = (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)). 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.
