Throughput of the water of shutter with flexible working bodies

Abstract

The author together with Bochkarev V developed a hydraulic automatic water level controller with flexible working bodies. To determine the throughput and determine the optimal profile shape of the weir of its shutter, experimental studies were conducted. They were carried out by the method of physical modeling of the model and nature in an experimental setup, with the study of three types of shutter models with flexible working bodies with the shapes of a part of the spillway in the form of a board, non-vacuum and elliptical vacuum profile. Based on the results of these studies, without and with a side stream, formulas and dependency curves are obtained for determining the flow rates of the spillway with three forms of its part of the spillway. An analysis of the results of the study showed that the shutter with the spillway non-vacuum profile without has a slightly lower throughput than others, but is characterized by stable operation without vibration and is therefore recommended for use.

“…Where b is width of the flight blocked by a shutter; h is pressure over a shutter crest; g is gravity acceleration, m р is the resulted factor of the expense defined under the following empirical formula of the author [10]. Flow from under the shutter flushing device in the absence of lateral outflow was determined by the formula (1) where µ is the coefficient of flow determined according to the schedule in Fig.…”
