Description

Technical field [0001] The invention relates to the technical field of liquid discharge, in particular to an experimental device for liquid discharge characteristics. Background technique [0002] The electro-hydraulic effect is a general term for the physical effects of heat, light, force, sound and other physical effects that are accompanied by high-speed capability conversion during high-voltage and high-current pulse discharge in a liquid medium. The electro-hydraulic effect is widely used in industry, such as mechanical processing and manufacturing, electric pulse cleaning, extracorporeal lithotripsy, and the production of underwater sonar equipment. Because of the advantages of environmental friendliness, high efficiency, and low cost by using the discharge technology in liquid (for example, water) to generate the hydroelectric effect, the research and application of discharge characteristics in water has attracted more and more attention. [0003] The discharge process in l...
