摘要：

One spiral generator is introduced to generate spiral flow in pipe flow, which can make it possible that material concentration is high, though the flow velocity is slow. The spiral flow is a complex vortex of compelled vortex and potential vortex, of which the source is dependent on itself energy. The vortex intensity is analyzed by means of fluid dynamics, and the paper also indicates that the Ros number is a good indicator to evaluate the vortex intensity, finally, a rule is concluded that vortex decays radically and longitudinally in the pipe.
