A numerical method for boiling flows, based on a finite volume/front tracking approach, is described. The method is used to examine film boiling and results from two simulations are discussed briefly. In one case the system is assumed to be two-dimensional and the breakup of many bubbles from the film is followed for a sufficiently long time so that it is possible to compute the average heat transfer rate. The other simulation is a fully three-dimensional system, but only one mode is followed for a relatively short time. In both cases the heat transfer rate is in reasonably good agreement with experimental correlations.
