| 摘 要： | 冲击伴随噪声是阻塞阀门噪声的重要成分。通常认为它是由阻塞喷注中的大尺度湍流结构和冲击气室的相互作用所产生的。分析表明,对于确定的管道系统和阀门上游驻压,存在一个确定的阀门开启位置。这时阻塞阀门喷注的冲击伴随噪声最强。

| Abstract: | The shock associated noise is an important component of choked valve jet.It is believed that the shock associated noise is emitted by the interaction between the large scale turbulent flow structures and the shock cell system in he jet.The studies show that there is a certain valve open area which emits the strongest shock associated noise after the determined pipe system and upstream stagnation pressure. |
