碩士 === 國立交通大學 === 機械工程系所 === 95 === In two fluid flow investigation, the simulation of flows with free surfaces is difficult because neither the shape nor the position of the interface can be identifies in advance between two immiscible fluids. The aim of this study is to develop a scheme, which ensures the preservation of the sharpness and the shape of the interface while retaining boundedness of the field, by volume tracking method and blending strategy without explicit interface reconstruction. The motion of the interface is tracked by the solution of a transport equation for a phase-indicator field. Furthermore, this scheme is formed and compared with the well-known HRIC, CICSAM and STACS schemes. Some favorable cases are simulated and comparisons are made in the literature.
