摘　　要：主要研究微管道内高分子湍流减阻。介绍了高分子湍流减阻理论发展的基本概述;详细介绍了高分子湍流减阻微通道实验的实验装置及有关做法,并对实验数据进行分析处理;通过分析实验数据,对减阻率进行拟合处理,建立起包含多种因素的实验模型,对影响减阻效果的各因子水平及其相互作用进行分析评价;通过实验值与计算值的对比,发现本模型能够很好地预测减阻率,误差大多在30%以内。In this paper,we focus on the drag reduction by polymers in micro-tube flow.At the beginning of the paper,we introduce the development of theory and mechanism of drag reduction by polymers.After that,we show the experimental devices and method,and analyze experimental data.We correlate drag reduction data and develop an empirical model to predict drag reduction which incorporates several factors and their interactions.Last,we compare drag reduction from the experiments and correlation,and it is found that most data can be predicted within 30% relative error.
