Abstract:Cavitation is an important factor causing vibration and noise of water-jet pump. High-performance ships require water-jet pumps with high efficiency and low noise at high speeds. At present, the cavitation flow phenomenon and interference mechanism of the water-jet pump under different flow rates are not clear enough. This paper takes the mixed-flow water jet propulsion pump as the research object. The flow structure of the cavitation vortex of the water-jet pump under different flow rates was obtained by high… Show more
