从流场分析初步探讨排沙漏斗的输沙机理

Study on Mechanics of Sediment Transport in the Sand Funnel from Its Flow Field Characteristics

简要分析了排沙漏斗清水流场特性，对排沙漏斗浑水流场进行了较系统的测试，通过清、浑水流场对比分析，证实排沙漏斗螺旋流具有使泥沙沉积并向漏斗中心输移的水流特性。

In this paper, the sediment free flow field and the sediment fluid flow field were analyed. The sediment fluid flow field, among them, was measured for the first time. And the difference of them showed that the flow field characteristics in the sand funnel were beneficial to sediment sinking and transporting.
