Abstract: This paper presents an overview of the theoretical and experimental investigations on the liquid flow in a liquid-filled container, including studies on inertial wave and its breaking-down, secondary flow, spin-up flow, critical layer, natural sloshing, large amplitude sloshing, wave breaking, drop ejection, bubble entrainment. As far as cylindrical containers go, the liquid-filled containers can be rotating and non-rotating. Some brief outlines on corresponding numerical methods and their applications are given. Furthermore, from the point of view of systems dynamic simulation, related problems of coupling systems dynamics of liquid-filled containers are discussed.
