Hydrodynamic pressure upon elements of the shutter with flexible working bodies

Abstract For automatic control of the water level in the part of the channel in front of the hydraulic structure, a hydraulic automatic water level controller was proposed. Its main element is a shutter with flexible working elements, consisting of a reservoir formed by a shield for draining water from the channel and flexible cloth. To ensure stable operation without vibration, experimental studies of this shutter with a spillway in the form of a non-vacuum profile were carried out. These studies were carried out by the method of physical modeling of the model and nature in an experimental setup. The aim of the study was to determine the hydrodynamic pressure acting on this shutter, the forces of hydrodynamic pressure, and the centers of application of these forces to the shutter in the form of a non-vacuum profile. Studies have shown positive hydrodynamic pressure on the spillway of the shutter, the absence of vibration, the stability of the shutter. The obtained dependences for determining the forces and centers of application of hydrodynamic pressure forces to the elements of the spillway part of the shutter allow us to calculate this shutter
