Abstract

This work deals with the computational and experimental investigation of the dynamic characteristics of the model Kaplan turbine blades. Experimentally and numerically eigenfrequency spectrum of the blade in the air and in the water has been determined. Also, the parameters of the damping of the blades and it frequency response have been obtained.
