Default Level Set in Cavitation Modeling

While looking for experience on level set function usage in cavitation modeling, I've found papers on rising bubbles and other free surfaces captured by a level set function, but -seemingly- few on cavitation bubble dynamics. The latter adding some complications such as bubble creation (inception), merging, rapid changes of bubble volume and the eventual bubble collapse.

I would be grateful for tips and references on the subject.

Applications of foams and foaming are found in many industries like the flotation of minerals, enhanced oil recovery, drilling in oil reservoirs, insulation, construction and refining processes such as Vacuum distillation and Delay-Coker reactors. However, foaming and defoaming are not yet understood. Foams trap gas and are not wanted in many applications. Guitian and Joseph (1997) proposed fundamental studies of their observations on foam suppresion experiments they carried out in a cold slit bubble reactor. In this page we present our most recent findings.
