Abstract
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.
