Dear sirs,


I'm beginning a CFD study of flotation cells used in mining industry. To simulate the dynamic behavior of that cells I need to work under the following characteristics:


- Turbulent model (RAS for now... maybe LES in the future if its necessary).
- Dynamic mesh to simulate the rotor movement.
- Free surface (slurry-air interface, but can be water-air for now) because I need to simulate the vortex in the center of the cell (near the rotor zone, like a mixer).
- Bubbles behavior in a future work (maybe with bubbleFoam).


So, for now 02/05/2020 (MM/DD/YY), I would like to know if a similar tutorial for OpenFOAM exists to begin the study with it. The most similar tutorial I've found is the following:

Regards,


Pablo.

Hi everyone;


I've found an appropiate tutorial case for OpenFOAM v7 in /opt/openfoam7/tutorials/multiphase/interFoam/RAS/mixerVesselAMI


As the name says, it is a mixer vessel simulation which uses an Arbitrary Mesh Interface (AMI: rotatory mesh field). I'm interested in the behavior of the air-fluid interface. The simulation of the vortex is an important phenomena for my study. I understand that without the surface tension simulation it's impossible to form a bubble (also because I would need an incredible refined mesh for that). So, I pretend in the near future to add some single bubbles to the simulation to study this phenomena. I supposed that I can made it using bubbleFoam.

The problem is very CPU expensive (solved in parallel with 16 cores). Even for an i9-9900k. It takes about 5 hours to simulate the vanilla problem. Tomorrow I going to change the vanilla geometry for the geometry of a flotation cell and see what happens.

Regards,


Pablo.
