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.
Czech abstract
V článku je uvedeno modelování vysokofrekvenčních tlakových a průtokových pulsací pro model čerpadlové turbíny s rozváděcími lopatkami. V matematickém modelu je uvažován vliv oběžného kola. Výpočet je založen na metodě přenosových matic. V článku jsou uvedena frekvenčně amplitudová charakteristika, vypočtené vlastní frekvence, vlastní a vynucené tvary kmitu tlaku. Výsledky matematického modelování jsou porovnány s experimentem.
