Abstract: This paper presents the relation between the tip leakage flow cavity and cavitation number on the blade flange in Kaplan turbine by experimental investigation. The tip leakage flow cavity in Kaplan turbine by means of experimentation under different cavitation number and different operating conditions has been investigated. The analysis focuses on the leakage vortex’s nucleation inception and growth under different cavitation number and operating conditions on the blade flange. The results indicate the effect of clearance cavitation and the rise of cavitation number in the Kaplan turbine.
