Hi CFD users,

I would like to use CFD to predict foaming formation in beer.
Does anyone have such kind of experience in this?
How would you model fluid "Beer"?
I would think of it as a fluid with dispersed CO2, but I have some doubts regarding physical properties to be modeled (density, viscosity, ecc...)


Thanks a lot for your kind suggestion.

Hi,
I think SPH is the best choice for this kind of simulations. Try to search the works done by Paul cleary, Australia. I saw his results, but is not sure that they have been published or not. You may find some open sources on SPH.
I noticed that his movies are still available on a public place.

Thanks for your suggestion.

I've taken a look at Dr. Paul Cleary work.
What I can't understand is if it can be applied as a prediction tool (and integrated in a cfd code) or is simply a Maya plug-in for realistic effects...

I mean SPH (a method) may be used for your project. I never use this method. Thus, you have to investigate it yourself, or get hints from someone else. If I remember it correctly, Paul also considered gas as particles in simulating beer flow in a cup. I always trace the works regarding SPH used for particle-fluid systems. But so far, there are not so many papers. This really means something. Maybe there are some uncertainties in handling particle-fluid or bubble-fluid interactions.
Good luck!

I don't know if this is going to help. But there's this in the Fluent web site:
Do the Bubbles in a Glass of Guinness Beer Go Up or Down?

Thaks Rui for your links.

I think these cases are "demonstrative" in order to get some small scale physical problems (bubbles - micron scale) and are sure interesting - so to speak maybe are developed for "commercial" purposes...

I think that foam formation could be related to this scale phenomena (bubbles rising) and hope to find a sort of model of prediction.
