探讨了产生圆管螺旋流的局部起旋器，并在模型试验的基础上，通过对两套起旋装置在不同流量下的轴向流速及周向流速以及起旋器结构参数的比较和分析，得到了更有利于圆管螺旋流输送的结构参数。

英文摘要：

This paper probes into the spiral generator that can initiate the spiral flow, and based on the model experiment and through the analysis and comparison of circumferential velocity and axial velocity of two sets of the generators under the different flows and the structural parameters of the generator, obtains the structural parameters that are more beneficial to the transportation of the flow.
