摘要

摘要通过实验和理论研究了铁流体在静止的非磁性外管和匀速直线运动的内圆柱形永久磁铁之间的同轴间隙中的粘性摩擦。在流量为零的库埃特-普绪耶流动曲线模型概念框架内，提出了有效摩擦系数的分析表达式，并在实验室实验中得到了证实。

Viscous Friction of a Ferrofluid in the Coaxial Gap between Cylindrical Walls Being in Uniform Rectilinear Relative Motion

The viscous friction of a ferrofluid in the coaxial gap between a stationary outer nonmagnetic tube and a uniformly and rectilinearly moving inner cylindrical permanent magnet was investigated experimentally and theoretically. An analytical expression for the effective coefficient of friction was proposed within the framework of the model concepts of the Couette–Poiseuille flow profile with zero flow rate and was confirmed in a laboratory experiment.
