摘要
管内液体的流动速度在超过临界流速后,流体与管壁之间会出现相对滑动。分析认为,滑移与减阻之间关系密切。给出了滑移模型以及影响减阻率的因素。
When the velocity of a fluid in a pipe is greater than critical velocity, slip will happen. The analysis shows that the ship has a close relation to drag reduction. In this paper ,the model and the factors which affect the drag reduction rate are given.
