Platonov, D. V. The study of the influence of stabilizing devices on the pressure pulsations at the free discharge of water through the turbine [Текст] / D. V. Platonov, A. V. Minakov, D. A. Dekterev // MATEC Web of Conferences. — 2017. — Т. 115.Аннотация:
The free discharge through the turbine is applied in the course of construction of hydro power plant or in case of excessive water inflow during floods or emergency situations. The experimental and numerical investigation of flow-induced pressure pulsations in hydraulic turbine draft tube at free discharge was performed using a special setup for suppression of draft tube surge. Such special equipment in draft tube cone as fins and "spider"-like units was considered for reducing these pressure pulsations. The paper considers influence of these units on vortex structures and pressure pulsations in the draft tube in several regimes.
