基于全模拟的水泵装置模型虹吸出水流道水力特性分析
Simulation analysis of the pump device model hydraulic performance of siphon discharge conduit
摘要
Abstract
Siphon outlet conduit is one of the main forms of outlet conduit of large pumping station .Due to the limitation of actual engineering topographic features ,the siphon outlet conduit adopted by the South‐to‐North Water Diversion Project - -Jiangdu NO .1 pumping station is not common in engineering design .According to the siphon discharge conduit in Jiangdu NO .1 pum‐ping station ,numerical simulation of the whole flow passage was conducted by CFX ,the internal water flow movement charac‐teristics of the siphon outlet conduit were studied and the hydraulic performance was predicted .The results showed that the lower head loss mainly came from the head loss of bending section .In outlet passage ,vorticity showed a downward trend ,but the cross section area was too large to cause the uneven distribution of the velocity of the outlet section and increase of the vor‐ticity .External characteristics of the pump device prediction results were consistent with the test data of the overall trend ,dem‐onstrating that the calculation results were reliable .关键词
