Concerning the characteristics of frequency and amplitude of pressure surge caused by whirl flow from the runner outlet of a Francis turbine, experimental investigations by model tests were made with the folloowing results.The relation between frequency under general situation and remarkable pressure surge and specific speed with wide range was made clear using the circulating velocity of flow from runner exit.A practical interpretation about tendency of increase and decrease of amplitude according to operating conditions and amplitude characteristics affected by cavitation coefficient was obtained.
