Numerical simulation of multi-phase flow is essential to evaluate the feasibility of a liquid protection scheme for the power
plant chamber. The level set method is one of the best methods for computing and analyzing the motion of interface among
the multi-phase flow. This paper presents a general formula for the second-order projection method combined with the level
set method to simulate unsteady incompressible multi-phase flow with/out phase change flow encountered in fusion science
and engineering. The third-order ENO scheme and second-order semi-implicit Crank­Nicholson scheme is used to update the
convective and diffusion term. The numerical results show this method can handle the complex deformation of the interface and
the effect of liquid­vapor phase change will be included in the future work.
