SIGGRAPH 2010: A Practical Simulation of Dispersed Bubble Flow

[fuelban]

Very interesting video, I am trying to resolve a problem with bubbles created in a small reservoir space, they keep getting sucked in to the circulating pump inlet, pass through the impellor, back into the reactor, & worsen the problem, filters just clog up with tiny bubbles then fail, the large air bubbles rise, whilst the small gas bubbles sink. MMM Help anyone!! LOL.

Can you please explain about k and v what it stand for. Thanks in advance

Awesome.

Very good!

What's it rendered in?

Kinda reminds me of

Wavelet Turbulence for Fluid Simulation

hxxp://cs.cornell.edu/~tedkim/­WTURB/

Is it based on this?

@steffensensa

Thanks!

I rendered it using mentalray in maya.

Our simulation method is quite different than wavelet turbulence.

It's based on bubble dynamics, rather than turbulence theory.

If you have more questions, please send me a mail.

Good job man! Really enjoyed the Sim!

Would Blender perform as well as Maya for this type of Physical Sim?

@Cryto Hi Cryto.

Thank you for your comment!

I rendered this video using Maya, but the simulator that I wrote is a standalone program, so it does not depends on any platforms.

I'm currently working on refining my simulator, and someday it will be open public, I hope :)

@doyubkim Yeah! I hope you can release the simulator or even the code, we would all benefit from it! Your simulation is looking pretty neat! How have you integrated your software on maya ? Through python ? Does it set all particles position ?

Cheers!

@gramulho Thanks gramulho!

My simulator interacts with maya thru particle files which I defined. The file contains position and radius of particles, and I made a simple maya plug-in to import/convert the file into a maya particle node. Recently, I'm working on reimplementing this routine so that the simulator can export particle info to the krakatoa format. I bet this could be better for the potential users, and in my case, mentalray was extremely slow for rendering particles :(

Looks great!

Jaw-dropping.
