Original Abstract

Paper presents computation of high-frequency pressure and discharge pulsations for model of pump turbine with guide vanes. Mathematical model of pump turbine with influence of the runner is described and computation by transfer matrix method is performed. Results are in form of frequency-amplitude characteristics of pressure, natural frequencies, eigen mode shapes and forced mode shapes of pressure. Forced mode shapes and frequency-amplitude characteristics are compared with model measurements.
