对充满静止不可压缩粘性流体的圆柱形，当柱壁沿垂直于柱轴方向作小振幅简谐振荡时的内部流动进行了实验研究，发现柱壁振荡在圆柱域内部也诱导形成旋涡形态的定常整流流动。流动图谱随不同的振荡参数组合呈现四涡形态、双涡形态以及足印状双涡和蝶状四涡的过渡形态，并初步给出了不同整流图谱随参数变化的演化规律。
For a cylinder filled with still incompressible viscous fluid, when the column wall is subjected to small amplitude harmonic oscillation perpendicular to the column axis, the internal flow is experimentally studied. It is found that the column wall oscillation also induces the formation of vortices in the cylindrical domain. Rectifier flow. The flow patterns show the four-vortex morphology, the double vortex morphology and the transition morphology of footprint-like double-vortex and butterfly-shaped vortex with different combinations of oscillation parameters. The evolution of different rectification spectra with parameters is also given.
