gated tunnel meaning in Chinese
闸门控制的涵洞
Examples
- Unsteady separated flow , produced during the gate - opening period in the reverse radial gate tunnel of a high - lift shiplock , is characterized by negative pressure and high velocity as well as their intense fluctuations in space and time and could easily result in various harmful phenomena such as cavitation , gate vibration and sonic boom , which have been observed and confirmed by prototype and physical model tests
高水头船闸输水反弧阀门开启过程中，后廊道内发生急变分离流，负压、高速水流以及压力与流速的剧烈时空脉动变化容易诱发空化空蚀、门振和声震等有害现象已被原型观测和物理模型试验研究证实。 - In this thesis work , a 1 - d hydraulic transient model and a 2 - d compressible flow model with the large eddy simulation approach have been applied to analyse the hydrodynamic process of the unsteady separated flow . prototype observation data of gezhouba shiplock no . 3 has been used to verify the computational results . it has been found that two different types of flow regime - stably - varying and strongly - oscillating regimes - could occur in the radial gate tunnel
本文采取将一维非恒定流模型与二维可压缩流一大涡模拟模型相结合的方法，分析了急变分离流的水动力学特性，并利用葛洲坝三号船闸的原型观测资料验证了数值模型的可靠性，发现阀门段存在平稳变化型和剧烈振荡型两种不同的流态，并详细计算、分析了它们的流动特征
