基于数值模拟的闸站结合布置优化设计
Layout design optimization of integrated pumping station and sluice with numerical stream simulation
摘要
Abstract
In water conservancy hub projects located at plains,usually the pumping station and sluice are integrated together for a compact layout to save land and reduce costing.However,this combined layout can result in unwanted flow patterns,such as locally reverse flow,strong lateral current and so on.Thus,as a case study,the asymmetrical layout of integrated pumping station and sluice in North Yaoguang Water Conservancy Hub Project is optimized and finalized based on two-dimensional numeri-cal stream simulations and a detailed discussion about the layout rationality and safety of navigation.It is shown that it is proper to install a diversion pier between the pumping station and the sluice upstream and downstream in order to alleviate uneven flow patterns and satisfy the safety of navigation.Additio-nally,the diversion pier can drive the reverse flow zones to further upstream and an increased length of the piers can reduce the velocity of lateral current.A trash rack bridge is installed in the intake of the pumping station to collect debris and improve flow patterns,causing an increased pump efficiency and operational stability.The results have significance for layout design in similar conservancy projects.关键词
