秦淮新河泵站前池流态改善措施研究
Research on improvement measures of flow pattern in fore bay of Qinhuaixinhe Pumping Station
摘要
Abstract
Using the CFD numerical simulation method and taking the Qinhuaixinhe Pump Station as the research object,a numerical simulation study on the flow pattern analysis and improvement measures of the forebay of the pump station is carried out.The results show that under the condition of ultra-low water level,there is a large area of recirculation zone near the diversion pier of the fore bay,which seriously affects the water inlet condition of the side unit,resulting in the flow velocity uniformity and weighted average angle of the side unit being much lower than that of the other units.The addition of circular water holes and Y-shaped diversion pier can improve the flow pattern in the fore bay,eliminate the bad flow pattern near the diversion wall,and improve the flow velocity uniformity and weighted average angle of the side unit.The research results can provide a reference for the design and transformation of pumping stations.关键词
