| 摘 要： | 经过十多年研究与总结，新疆农业大学相继推出了两种不同型式的排沙漏斗结构形式，分别用于排除来流中的推移质及悬移质泥沙。模型试验及部分原型观测的资料表明，其排沙效果好，且耗水量小。本文首次利用激光多普勒测速仪（ＬＤＡ）测试了其中一种结构形式排沙漏斗的三维螺旋流流场，对其时均流特性及紊动特性进行了分析和研究。同时还分析了其对输沙过程所产生的影响，为进一步优化此类型排沙漏斗的体型打下了基础

| Abstract: | The sand funnel has widely applied to the projects of sediment transport in recent years. In this paper, the flow field of 3-D screw flow in the sand funnel was measured by advanced instruments(LDA). The analysis of mean-flow structure and turbulence structure in the flow field were conducted. Meanwhile, authors analysed it's influence on sediment transport in the sand funnel. The research is beneficial to optimize the sand funnel geometry. |

| Keywords: | sand funnel screw flow characteristics of mean-flow characteristics of turbulence sediment transport |
