| Abstract: | The mechanism of drag reduction by ejecting compressed air into pipeline is analyzed. The factors affecting drag reduction are researched in the model test, and the effect on pipeline transportation is deduced. It is found that, by ejecting compressed air to clredger pipeline, the transport resistance can be reduced and the discharge distance of pipeline transportation can be extended. |

| Keywords: | pipeline air ejection for easy transportation drag reduction discharge distance dredger |
