抄録

A numerical analysis method using the level set method has been developed to simulate the interface movement and growth with phase change which accompany a change of density. The multi phase flow and the temperature with the latent heat are solved by the finite volume method on a fixed non staggered Cartesian grid. Particular treatments added to the level set method to calculate the Stefan condition and the remedy added to the temperature equation to avoid the artificial temperature advection beyond the interface are described in detail. Our analysis method is capable of both the solid liquid and liquid gas phase changes. Good agreements of the interface location with other published results and better accuracy in temperature and velocity distributions are obtained, though some errors still exist in the growth rate of the interface in each direction from the effect of the Cartesian gird.
