摘　　要：该试验选择了两种圆管螺旋流局部起旋器方案,并在不同流量工况下分别进行了试验。在试验的基础上,对其管段内的流速分布与压力分布进行了分析,从而揭示了起旋器管段内流场分布的特性。为实际运用螺旋流输沙技术解决泥沙淤积问题提供了理论依据。The pilot study of the model chooses two kinds of programmes of the spiral flow generator in the circle pipe. Under different flow operating mode, the study proceeds respectively, on the base of experimental study, the flow velocity distribution and pressure distribution in the experimental section of circle pipe are studied in this paper, it makes the distributive character of the flow clear. The study offers theoretical foundation for the problem that the technology actually solves the puzzle of fall sand in the pipe.
