All the machinery to do this is in Fluent, but this simulation is not practical on an industrial scale. The bubble collapse ( implosion part of the cavitation lifetime) will lead to an abrupt reduction of the bubble volume. The gas inside dissipates explosively into the surrounding liquid, along with a large heat release and pressure increase. This will lead to the propagation of an acoustic wave and generation of light. The latter part of this process is not manageable from a CFD perspective. The study of a individual bubble could perhaps be done as with an extremely fine mesh, but this is not an industrially practical solution.
