Abstract: This paper presents an overview of the theoretical andexperimental 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 ascylindrical containers go, theliquid-filled containers can be rotating and non-rotating. Some brief outlines on corresponding numerical methods and theirapplications are given. Furthermore, from the point of viewof systems dynamic simulation, related problems of coupling systemsdynamics of liquid-filled containers are discussed.
