摘　　要：间隙中充满流体的同轴转子可简化为经典的Taylor-Couette流动模型,该模型具有结构简单、对称度高和便于开展高精度实验测试等特点,被广泛应用于基本流体力学问题研究。涉及Taylor-Couette流动的转轴类结构在工程领域普遍存在,开展Taylor-Couette流动特性与减阻方法研究具有重要的经济价值。本文系统地介绍了Taylor-Couette流动的主要无量纲影响参数、流场结构和扭矩特性;总结了基于Taylor-Couette流动减阻方法的研究进展,并根据减阻原理将其划分为通用减阻方法和特有减阻方法2类;最后对Taylor-Couette流动减阻研究进行展望,为后续研究工作提供参考。The coaxial rotor filled with fluid in the gap can be simplified to be the Taylor-Couette flow model.It has the characteristics of simple structure,high symmetry,and easy to carry out high-precision experimental tests,and is widely used to study basic fluid mechanics problems.Rotary shaft structures involving Taylor-Couette flow are ubiquitous in the engineering field,and research related to Taylor-Couette flow characteristics and drag reduction methods has important economic value in the engineering field.In order to facilitate researchers to understand the experimental progress of Taylor-Couette flow characteristics and drag reduction,this paper systematically introduces the main dimensionless influence parameters,flow field structure and torque characteristics of Taylor-Couette flow.According to the differences in drag reduction mechanisms,the drag reduction methods can be divided into two categories:the general and the specific drag reduction method.Finally,the prospect of the research on Taylor-Couette flow drag reduction is given,which provides reference for future research work.
