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 ("libreactingEulerFoamFunctionObjects.so");
|
|
writeControl writeTime;
|
|
writeInterval 1;
|
|
|
|
...
|
|
|
|
phaseName water;
|
|
}
|
|
\endverbatim
