Purpose of work is receipt of tekhnikal-ekonomical effect in industry at development of running parts of high-pressure hydroturbines of RO200-1000 and pryamotochnykh hydroelectric generators on pressures 40-250 meters due to creation of mathematical models of the optimized workings processes, determinations of their characteristic conformities to law and non-stationary phenomena on the basis of hydrodynamic analysis of the real structure of stream in ductings of hydro-turbines, that will allow considerably to increase KPD, to promote reliability and and longevity during exploitation. Methods of research -- mathematical modeling based on modern software, an experimental research method that is used in GT some energy datum determination and in determination of amplitudes and frequencies of caused by turbine vortex bundles pressure pulsations and with application of modern strain gauge instrumentation on models and on a real object. Implementation of research work results on hydroelectric power station of Ukraine can cause a significant economic effect, which can be up to 25-30 million U.S. dollars a year. Scope of the research results use - power engineering. Product Description popup.authors Гасюк О.І. Дранковський В.Е. Зав'ялов П.С. Количев В.О. Крупа Є.С. Кухтенков Ю.М. Лур'є З.Я. Миронов К.А.
