Abstract
We introduce a model of cavitation based on the multiphase Lattice Boltzmann method
(LBM) that allows for coupling between the hydrodynamics of a collapsing cavity and supported
solute chemical species. We demonstrate that this model can also be coupled to deterministic or
stochastic chemical reactions. In a two-species model of chemical reactions (with a major and a
minor specie), the major difference observed between the deterministic and stochastic reactions
takes the form of random fluctuations in concentration of the minor species. We demonstrate that
advection associated with the hydrodynamics of a collapsing cavity leads to highly inhomogeneous
concentration of solutes. In turn these inhomogeneities in concentration may lead to significant
increase in concentration-dependent reaction rates and can result in a local enhancement in the
production of minor species.
