经过多年的理论与实践研究，螺旋流排沙已被广大的水利工作者所认可．本文首次利用毕托球测速系统测试了由新疆农业大学最新推出的带导流墩排沙漏斗的三维螺旋流流场，对其时均流特性进行了分析和研究．其次，文中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流态打下了基础 After years of theoretical and practical research, spiral sediment discharge has been recognized by the majority of water conservancy workers. In this paper, for the first time, the three-dimensional spiral flow field of sand hopper with diversion pier, which was newly introduced by Xinjiang Agricultural University, was tested by using the Biot ball velocity measurement system. The current-flow characteristics were analyzed and studied. Secondly, the article also analyzes its impact on the sediment transport process, in order to further optimize this type of funnel flow pattern laid the foundation
