Hello everyone,

I want to know the path of different particles injected at the entrance of a domain.

These paths are only based on the velocity field. No contact between the particles is to be calculated. They have no mass and a very large entrainment coefficient. In fact it is the path of some molecules of the liquid that flows in the calculation domain.

I use Openfoam V11, the calculation domain is composed of a fixed part (stator) and a rotating part (rotor). The continuity is done by NCCs. The simulation is unsteady and two-phase.

The whole thing is similar to a mixer, in which we would like to know the exact path and the position at each iteration, of some particles of one of the liquids. Nothing too bad.

I don't know which solver to use.

Can someone help me?


Thank you for your help
