沿程起旋式螺旋管流阻力研究

Research on the resistance of the spiral pipe flow with continuous rotation

圆管螺旋流输移固粒是一种新型的高浓度、低能耗管道输送方式。通过在管道中增设导流片来形成圆管螺旋流必然增加水流的能耗 ,本文从理论与试验方面确定了清水螺旋管流的能耗 ,为螺旋流的工程应用提供一些技术参数。

Transporting sediment by spiral pipe flow is a new style which possess high concentration and low energy loss.It is inevitable that the energy consumption increases with setting up of the guide vanes.This paper analyzes the resistance of spiral pipe flow by theoretical and experiemental studies.It provides some technical parameters for engineering appcication to the spiral pipe flow.
