A high-speed jet is formed in the bubble due to the convolution of the fluid on the boundary of the bubble . 由于在气泡边缘上流体的回旋,在气泡中形成了高速射流。
On arrangement forms of waterproof high - speed jet condensing bodies between supporting piles 浅议桩问止水高喷凝结体的布置形式
A comparison of the flows with different gate - opening rates shows the causes that opening the gate at a higher rate is favorable to the reduction of cavitation , gate vibration as well as the gate load fluctuation . in addition , a study has been made to show the influence of the high - speed jet flow coming downward from the narrow gate gap on the flow condition in the tunnel downstream to the gate 通过分析比较不同阀门开启速率对流动特性的影响,阐明了快速开启阀门不仅有利于减少空化空蚀也有利于减小弧门振动和启门力的脉动,此外,研究了门楣处狭窄缝隙高速射流对门后流态、压力脉动和弧门受力等方面的影响。
