For the establishment of fluid management technology under low gravity conditions, the investigation methods with computational fluid dynamics are strongly desired to give appropriate assessment of designed systems for space application. In the present study, a numerical analysis method with C-CUP scheme coupled with Level Set method and CSF model was developed to simulate incompressible and compressible two-phase flows including surface tension effect, adhesion phenomena and gravity effect. By the application of CIP scheme to the re-initialization and advection of the level set function, the shape of curved interface between gas and liquid phases could be distinctly captured, and the surface tension was adequately estimated as a body force. With the developed code, the flow fields in a liquid tank under low gravity conditions were successfully simulated.
