Class
Foam::functionObjects::phaseForces
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:
\verbatim
phaseForces.water
{
type phaseForces;
libs (reactingEulerFoamFunctionObjects);
