Under the limiation of ship space, it is the key of ship design to improve the comprehensive performance of propeller. Cavitation is the main noise source of water-jet propulsion pump, so it is an important design parameter of water-jet propulsion pump. In order to reduce the noise of the ship and improve the cavitation performance of the water-jet propulsion pump, it is necessary to study the evolution law of the cavitation flow structure and its influence on the pump performance. In this paper, the evolution mechanism of cavitation flow structures in the critical cavitation conditions of water-jet propulsion pump is captured by high-speed photography. The cavitation flow structures of the water-jet propulsion pump during the occurrence and development of cavitation include sheet cavitation, cloud cavitation, tip leakage cavitation, tip vortex cavitation and vertical cavitation vortex. The experiment captures the physical process of cavitation evolution and the effect of each cavitation flow structure on pump performance degradation is analyzed. Combined with simulation and previous research, this paper further expounds the formation mechanism of cavitation flow structure and its influence on the pump performance.The research results not only provide new understanding of the cavitation phenomenon in the water-jet propulsion pump, but also provide reference and guiding significance for the study of cavitation performance prediction methods.
