Numerical method for thermal and fluid flow with free surface and phase change has been developed. Equations of continuity, Navier-Stokes and energy are solved simultaneously both for liquid and vapor phases. The calculation result of one-dimensional solidification problem agrees with Neumann's theoretical value. In the evaporation of liquid film, the flow caused by volume change with phase change can be calculated. We applied it to a bubble growth in superheated liquid and obtained the result that a bubble grows with spherical shape. The present method can be applicable to various phase change problems.
