中庄水库泄流出口消能研究

Study on energy dissipation of Zhongzhuang reservoir's outlet discharge

中庄水库泄流出口消能设计采用多喷孔无控制泄流的新型消能方式,多喷孔淹没对称向四周喷射出流,通过水与水、水与侧壁的碰撞进行消能.通过模型试验研究表明,其消能率达到87%,消能效果显著,且结构简单,可供类似工程参考.

A brand new engineering structure, submerged symmetry multiple orifice pipe with uncontrolled jet flow, has been adopted for energy dissipation of outlet discharge in Zhongzhuang Reservoir. This method uses water to water and water to wall collision to dissipate energy of uncontrolled jet flow. Model test shows this structure has remarkable energy dissipation rate, which is 87%. This simple and high energy dissipation rate structure could be used in similar projects.
