This paper describes two topics for a vibration problem and a active control technique for system with free liquid surface. The first topic is an unstable vibration of overflow pipe due to discharged fluid flow. This system has a horizontal and a vertical unstable vibrations caused by discharged fluid flow from liquid free surface into the overflow pipe. In this study, we investigated characteristics of these unstable vibrations by theoretical analysis and experiment. The second topic is an active control technique for the suppression of sloshing based on flow control in the vessel. We proposed active feedback control methods by using movable plates which are set in liquid. The performances of proposed methods are experimentally evaluated by time histories and flow visualization in the vessel.
