Research of simulation dendritic growth of xenon by phase field method

Numerical simulation based on phase field method is developed to describe two dimensional solidification of pure material,the evolution of the interface morphology is showed and the effects of phase field parameters are formulated for xenon.The results indicate that,with increase in undercooling,a small nuclei will grow developed dendritic,the tip velocity at steady state is become faster;With increase in the coupling parameter,tip velocity at steady state increased monotonically and it's interfacial stability is worse.
