Multiphase fluid simulations
Implement multiphase fluids including:
- Grid-based two-phase flow
- Both smeared Song et al. 2005 and GFM Hong and Kim 2005
- Grid-based multiphase (more than 2) flow Losasso et al. 2006
- Grid-based bubbly flow Kim et al. 2010
- Particle-based multiphase flow Yan et al. 2016
@marcelsan, let's discuss this issue and see how we can implement each solver. The references are not complete, yet. Also, please let me know if this is aligned with your original thinking.
Question: Is it possible to add the following effect in the future?: https://youtu.be/5h6UAjB4Xjo
Air incompressibility. To air was the second phase. There is a code, for example: https://github.com/ryichando/shiokaze
And more interested. It is possible to realize multiphase fluids, like here: https://youtu.be/TawnuP5xPo4 https://youtu.be/3yyLIG935zc?t=191
Two-phase fluid is planned but didn't have enough bandwidth to implement it. I do have my old personal code that implements a couple of papers mentioned above -- one of the papers is mine anyway -- but I need time to port it over. @PavelBlend if you want this feature, I can bump up the priority.
Yes, I would like to see this feature. Since I use jet fluids for a blender. And for the blender there is not a single multi-phase simulator.
Sounds fair. The first iteration will be similar to http://research.nii.ac.jp/~rand/shiokaze-en/index.html. No particles, but with level-set only. Two-phase PIC/FLIP/APIC would come next. Not sure I want to implement multiphase SPH, but it will be the last if I do.
