Synthetic Research on Hydraulic Characteristics of Culvert Shapes behind Valve for Three Gorges Ship Lock
-
摘要: 三峡船闸阀门段廊道体型一直是船闸单项技术设计的焦点。针对底扩与顶扩两种廊道体型,通过多项模型试验,从水力特性、空化及振动特性等方面论证了三峡船闸采用底扩廊道体型的优越性。Abstract: The selection about culvert shape behind valve is one of the key problems in hydraulic design for Three Gorges ship lock.Comparisons of hydraulic natures such as flow pattern,pressure fluctuation,cavitation,and vibration between two kinds of culvert shape behind valve,top expansion and bottom sudden expansion,are carried out in this paper.Due to the obvious difference,bottom sudden expansion culvert is used in Three Gorges ship lock,which can fulfill the operating conditions of filling valve.
