Hi,

Is it possible to simulate settling of solid particles suspend in liquid?

Thanks!

Track one particle or 'many'?

settlingFoam in anycase would be a good start. BubbleFoam can also be modified for this purpose.

alberto will become famous soon enoughalberto will become famous soon enough
twoPhaseEulerFoam should be easier to adapt to your purposes than bubbleFoam because it already contains two particle models:

- Normal stress modulus
- Kinetic theory approach (which is not yet very stable)

Best regards,
Alberto

Thanks guys!

In reality, there are several thousands solid particles suspended in liquid. I will be happy to track maybe 10 particles. I will look into settlingFoam first.

Well, with the codes aforementioned, no particles is tracked, they all use a eulerian approach. Assuming that with several thousands of particles you have a dense two-phase flow, either can be chosen.
SettlingFoam : based on drift flux model with mixture equution for mass and momentum
twoPhaseEulerFoam/bubbleFoam: two-fluid models.
