摘要
圆管螺旋流输移固体颗粒是利用螺旋流将推移质转变成“悬移质”的一种新的高效输移固粒的方式。文章侧重讨论螺旋管流输移固粒的特征机理与起旋器效率的测试与计算方法。初步试验表明，利用管内导叶式起旋器可有效地形成管道螺旋流。
It is a new and high efficient way to transport sediment by spiral flow in the circular pipe.The characters and mechanism of the transport way,and the calculation and measurement method of the efficiency of the pipe cyclone are presented.The preliminary tests show that the pipe cyclone can be effectively used to form the spiral flow in circular pipes.
