摘要
设计建造了管道输送加气减阻与助送研究的试验台,分析了加气减阻的机理和延长排距的效果,研究了影响试验效果的因素。试验结果表明,在排泥管中以适当的方式加入一定的空气,可以达到减少管道输送阻力和延长排距的作用。
The experiment device was designed to research drag reduction and help transportation, and the mechanism of drag reduction by ejecting compressed air to pipeline and the effect of helping pipeline transportation were analyzed. The experiment shows that it can carry out drag reduction and extend the discharge distance of pipeline transportation.
