Open channel energy dissipation method for jet flow stable hydraulic jump
The invention discloses an open channel energy dissipation method for stabilizing hydraulic jump through jet flow, relates to the technical field of open channel structures in hydropower station engineering, and aims at forming jet flow in the oblique upstream direction at the position, not smaller than the free hydraulic jump length L, of the downstream of a gate under the normal operation working condition of an open channel, and stabilizing hydraulic jump energy dissipation through the jet flow. The hydraulic jump occurrence area can be effectively controlled in a jet flow mode, so that the cavitation and cavitation erosion risk of water flow in the stilling pool is reduced, stable energy dissipation is achieved, and the problems of periodic maintenance and reconstruction are solved; the jet flow amount and the jet flow angle can be effectively adjusted through the simple jet flow adjusting assembly, and the jet flow adjusting assembly can correspond to the hydraulic jump conditions of the open channel under various operation working conditions through a method with high adaptability.
