Hello everyone.

I was searching in the Forum and at other places, but I didn’t find good explanation, so I opened this thread here.

What I want to do is simulating particles (oil) in a air-flow in a filter.
Right now, I am running a test case with a easy geometry with the icoFoam solver and VOF-Method. It is a two-phase-flow but to reach my goal I must implement the particles

The best thing would be to control the size of the particles with a binomial distribution before running the simulation. I also need to control the starting point und the density of the particles.

Right now, it is not completely clear to me which steps I must follow in which order to get what I want. Not even if I still can use the same solver.

If someone made this before I would be very happy for explanations and also for sending me the file (I can give you my email by PN). If you know a tutorial for this, please send me a link.

Thank you
Simon

Hello,


I am still having the same problem.
You can tell me if you need any further Information.


I read that DPMFoam or MPPICFoam is good for simulating particles.
What the difference between them?


There is also another Solver called reactingParticleFoam.
Is it true that it already has included coalescence?


Thank You
Simon

Hi,

- I am illiterate on these topics, but you may want to see the links below.
- Also this one: https://www.openqbmm.org/

Sorry for no good help.

MPPIC has the model implemented which does not need direct collision calculations between particles. Only interesting if we have a lot of particles inside one cell. I forgot the meaning which is somehow, multiple packed particle in cell. Using DPMFoam, you need to resolve each collision. In MPPIC you have an approach for that. The reactingParcelFoam allows one to use reactive particles rather than solid and nonreacting ones. Used for, e.g., evaporation of water droplets or what ever.
