Detailed Description

This function object 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 reactingEulerFoam solvers.

For a simulation involving more than two phases, the accumulated force is calculated by looping over all phasePairs 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 (reactingEulerFoamFunctionObjects);
    writeControl    writeTime;
    writeInterval   1;

    ...

    phaseName       water;
}
