A numerical method to track a vapor-liquid interface was explored for the film boiling heat transfer from a downward facing plate, based on the SOLA-VOF method. In order to take into account the effect of the compressibility, the LC (limited compresibility) method was modified to be applicable to phase change problems and incorporated into the SOLA-VOF method. The numerical solutions were obtained for the film boiling of saturated water at the atmospheric pressure. In the present calculation the thickness of the vapor film at the edge of the heated plate was determined with reference to the analysis of Shigechi et al. and Nishio et al., and treated as constant. Also, the Nusselt number was examined in comparison with the semi-empirical equation based on the Nishio et al.'s correlation.
