摘　　要：采用理论研究与湍流试验相结合的方法,以减阻增输为研究目的,通过分析流体与高聚物分子的相互作用,发现高聚物减阻的机理在于能够有效地抑制管壁附近流体的径向脉动。研究了减阻效果随各影响因素的变化规律,并展示了最新的研究成果,提出了可应用于实践的具体结论。Using the combination of theoretical study and turbulent flow test,with the purpose of drag reducing and flow increasing,this article analyzes the interaction between fluid and polymer molecules.It was found that the mechanism of drag reduction of polymer can effectively suppress the fluid near the pipe wall.At the same time the law of drag reduction with various influencing factors was studied and the latest research results were presented.At last concrete conclusions that could be applied to practice were put forward.
