Detailed Description

This functionObject calculates and outputs the blended interfacial forces acting on a given phase, i.e. drag, virtual mass, lift, wall-lubrication and turbulent dispersion. Note that it works only in run-time processing mode and in combination with the multiphaseEulerFoam solver.

For a simulation involving more than two phases, the accumulated force is calculated by looping over all interfaces involving that phase. The fields are stored in the database so that they can be processed further, e.g. with the fieldAveraging functionObject.

Example of function object specification:

phaseForces.water
{
    type            phaseForces;

    libs ("libmultiphaseEulerFoamFunctionObjects.so");

    phase           water;
}

Usage

Property	Description	Required	Default value
`type`	type name: phaseForces	yes
`phase`	Name of evaluated phase	yes
