Performance Simulation of a High-Speed Water Jet Device

摘要: 为了研究水下武器高速水喷流噪声问题，设计了高速水喷流实验装置，并运用相关理论建立了整个装置实验过程的数学模型，并进行了数字仿真，求取了实验过程中气瓶和气水缸的压力以及水喷流速度的变化规律。仿真结果表明，该方案可在一定时间内保持喷口高速水流速度的稳定性，可以满足实验要求，为下一步的实验研究提供参考。Abstract: To investigate the water jet noise of high-speed underwater weapon, we design a high-speed water jet device for experiment,and establish four models,including gas state model of supplemental cylinder,gas flow model of connecting pipe,gas state model of pneumatic-hydraulic cylinder, and hydrodynamic model of nozzle.We obtain the change rules of pressure from gas cylinder and pneumatic-hydraulic cylinder and water jet speed by numerical simulation.The results show that the device can keep stable high-speed water jet at nozzle within a certain period, and satisfy the demand of the experiment.
