Particle calculations

I am a university student and I am currently using OpenFOAM.
I would like to observe the behavior of particles in a two-phase condition of water and air, while rotating a propeller.
I would like to use dynamicMesh to rotate the propeller, but I can't find any solver for the above condition.
I compiled a new solver called MPPICInterDyMFoam based on a website, but it didn't work because the particles were trapped in the AMI.

Is there any possible solution? I would be grateful for your help. Thank you very much.

i have similar goal with you, i tried using multiphaseEulerFoam in openfoam v9. in the tutorial case it can calculate dispersed particle based on population balance equation, you can read the article here https://openfoam.org/guides/populati...ance-openfoam/ the dispersed particle tutorial is in titaniaSynthesis case.

i'm interested in your solver too, can you share it with me? maybe we can discuss because our cases is slightly similar, thanks

Thank you for your reply.
If you don't mind, can you show me the results of your analysis with multiphaseEulerFoam, the constant file, etc.?

I have compiled MPPICInterDyMFoam similar to the link below.

However, the particles were blocked by AMI and did not go up.
Here is a video.

This is a constant.

This is a system.

I still working and learning on it. so far i have learned that this solver can perform population balance modelling by leveraging the phaseProperties on constant directory. In the phaseProperties we define the phase class and its diameter.

Then, to get the population/NDF from specific region, we must define the region on a topoSetDict file located in system directory.

I haven't analyzed deeper about the stability and/or the validation of this solver, thus i don't know the mathematical properties analysis
