Problems solved by technology

[0004] At present, water conservancy cavitation devices mostly use Venturi tubes or porous plates with constricted throats as cavitation reactors. There are few reports that cavitation is generated by spoilers of different shapes, and it is difficult to achieve real-time observation of cavitation cavitation areas. The incoming liquid cannot be buffered and rectified, and it is even more difficult to ensure the strength and stability of the cavitation. Therefore, it affects the performance of the cavitation reaction device and limits the further promotion and application of the hydraulic cavitation technology.

Abstract

The invention provides a hydrodynamic cavitation generating device. The hydrodynamic cavitation generating device comprises a buffering body, a rectifying pore plate, a rectifying body, a rectifying grid plate and a testing body which are connected by flanges in sequence, wherein the testing body is a fluid channel which is composed of a shell and a ladder-shaped bottom plate and has a square cross section; three observation windows which are as wide as the fluid channel are opened on front, back and upper sides of the testing body; a bottom plate is split and is provided with a turbulent flow platform. A coming liquid sequentially passes through the buffering body, the rectifying pore plate, the rectifying body and the rectifying grid plate, the turbulence intensity can be reduced and the stability of water flow is enhanced effectively, so that the coming liquid can stably enter the testing body. The hydrodynamic cavitation generating device is simple in structure, convenient to detach, high in structural strength and good in impermeability; a test piece and the turbulent flow platform are convenient to replace; the distance between the test piece and the turbulent flow platform is convenient to adjust; the turbulence intensity is small and the cavitation strength can be adjusted continuously; the cavitation property can be observed directly and easily.

Description

technical field [0001] The invention relates to a cavitation generating device, in particular to a hydraulic cavitation generating device suitable for use in hydraulic structures and ships. Background technique [0002] Cavitation refers to the process of the formation, development and collapse of vapor or gas cavities (cavitations) inside the liquid or on the liquid-solid interface when the local pressure in the fluid (liquid) drops. Since the discovery of cavitation on propeller blades in the second half of the 19th century, people have continued to study cavitation and cavitation erosion, and gradually realized that it is a multiphase, transient, and microscopic complex process, which has a great impact on hydraulic engineering. Buildings, ships, aerospace, aviation, etc. are very harmful, but so far the mechanism of cavitation cavitation has not been clearly studied, so scientific and technological workers from various countries are eager to conduct in-depth research on ...
