Problems solved by technology

Among them, the research on cavitation and cavitation erosion characteristics of diesel engine nozzles is mainly based on on-site prototype experiments. The common problem of this type of equipment is that only one nozzle structure can be studied at a time, and the experiment takes a long time. Multiple experiments are required for nozzles with different structures. Multiple experiments will lead to differences in experimental conditions and affect the accuracy of the experiment

Description

technical field [0001] The invention relates to the technical field of hydraulic cavitation and cavitation erosion, in particular to an experimental platform capable of synchronously measuring cavitation and cavitation erosion phenomena in different nozzle structures. Background technique [0002] Cavitation erosion is the formation and collapse of cavitation bubbles in the liquid medium due to local pressure changes under certain ambient temperature conditions, and the material is continuously damaged by the impact of high-pressure and high-speed micro-jet flow on its surface. For a long time, cavitation has seriously affected the performance and service life of drainage structures, hydraulic machinery (water pumps, water turbines, gates, and ship propellers. Cavitation involves many fields, such as aerospace, national defense, navigation, chemical industry, atomic energy, and even biology and medicine. etc., and become one of the problems encountered in these fields. At pr...
