【摘要】 介绍了扬州瘦西湖水质治理中的引水系统试验。该试验采用变态模型,运用流体力学中的相似理论设计了模型试验的输水管路。试验模拟了引水系统在各种情况下的压强和水力损失,并对虹吸现象进行了仔细的观察和测试。试验表明该引水系统的设计合理,运行稳定可靠,水头损失小。该试验对各地城市水环境改善工程具有较强的指导意义。更多还原

【Abstract】 This article describes water-carriage system experiment of water quality purification in Yangzhou Slender West Lake.This experiment uses the state-variable model.It designed the model experiment hydraulic pipe-line using hydromechanics’s in similarity theory.This test study pipeline pressure and head loss under each kind of operating mode,also carefully observed and tested the Siphonage.Experiments indicate the water-carriage system is reasonable,and the operation is stable with low head loss.The test have stronger directive significance to water environmental improvement project in the similar city.更多还原
