| 摘 要： | 在中小型水利工程中,低堰应用是十分广泛的.而目前有关低堰的水力设计方面,包括设计准则和有关参数的选择,由于研究较少,只能延用高堰的一些标准和经验,导致设计的经济、合理受到影响.采用数值模拟可方便地对低堰的水力特性进行研究,节省工程时间和成本.文中采用Realizablek-ε两相紊流模型、VOF自由液面处理,对低堰进行...

| Abstract: | Low weir is widely used in medium and small water conservancy projects.However,few studies are made on hydraulic design of low weir including design criterions and parameter selection,which results in less economic and reasonable low weir design derived from standards and experience of high weir.In order to save time and cost,the method of numerical simulation is introduced.Base on realizable two phase turbulent model and VOF method,this paper studies the relativity of the height and discharge coefficient i... |
