Abstract
In order to control the noise and vibration of shipboard seawater system,the paper analyzes the main noise source of water injection system.Based on the formation mechanism of cavitation noise and turbulent noise,the optimal design of the three stage throttle depressurization was proposed to ameliorate the system pressure distribution and turbulent intensity.The flow field and sound field of single stage and three stage throttling system was simulated.The simulation results show that the noise of the improved system has dropped significantly to reach the expected noise control goals.关键词
