Film boiling is computed with the VOF method in FLUENT, which is modified to include the effect of phase change a t the liquid-vapor interface. The phase-change effect is implemented in the volume fraction and energy equations as the interfacial sources terms. The phase-change formulation is validated with 1-D analytic solutions of Stefan problem. The present method is applied to 2-D film boiling on a horizontal surface. The numerical results are compared with the empirical correlations.
