It reminds of an old tutorial of wall boiling where VOF model has been used. But sincerely hear to my colleagues (rwoolhou) suggestions if you really want to investigate it thoroughly. If you want just to have animations you can use Mixture Model with Lee Model for Phase Change, use IAC Gradient or VOF with UDF, play with URF and reduce time steps which need to resolve the Taylor-Rayleigh time scale.
