挟沙螺旋管流的沙质断面分布

Cross Section Distribution of Grains in the Spiral Pipe Flow with Sands

通过实验,对螺旋管流中沙质断面分布情况进行了讨论,进一步证实了螺旋流能有效地输送固粒,造成“悬浮”的气氛,不易淤积的特点。为高浓度、低能耗。

The paper discusses the cross section distribution of grains in a spiral pipe flow via experiments.It proves that spiral flow can efficiently transport grains,create the circumstance of suspension,and decrease deposition.It provides a reliable experimental evidence for sediment transport with high concertration,low energy consumption,and long distance.
