Abstract

type:text

This paper describes experimental study on the stability characteristics of a rotor partially filled with water. Constant amount of water is aupplied to the rotor continuously and is discharged radially by centrifugal force. Consequently, the rotor becomes unstable for some rotating speed range. The unstable speed range depends on the water supply rate as well as the amount of water in the rotor. Formardly traveling surface waves are also observed while the rotor undergoes an unstable orbital whirling motion. The wave travels at the same frequency as the rotor vibration frequency. As the water supply rate increases, the rotor becomes more stable.
