Experimental Investigation on Operation Scheme Optimization of Complex Sand-flushing System of Intake
摘要
Abstract
Complex sand-flushing system results in the disproportion of discharge through each outlet and the disparity of each funnel range.Simultaneously,hydraulic characteristics in connection part between sand-discharging outlet and the gallery is very complicated.Therefore,it is very difficult to achieve wide funnel range and good pressure characteristic by the simple operation schemes while keeping the form of sand-flushing structure.Based on hydraulic model test of sand-flushing system in the intakes of Longtoushi hydropower station in Dadu River,operation schemes were studied by physical models.The results revealed that the funnel range can be wide and pressure characteristic be good by means of changing operation scheme of the sand flushing system,which has important engineering and economic impacts for designing operation scheme of similar sand-flushing system of water intake.关键词
