通过观察改变偏心距和轴向流量对高速滑动轴承中泰勒涡产生的影响，研究了泄漏对高速滑动轴承中泰勒涡产生的影响。该装置允许尖锐和平滑地进入瓣环。流动可视化通过悬浮在测试流体中的铝涂料颜料实现。结果表明，偏心率和轴向流对临界泰勒数都有显著影响。两个系统的涡环内的共存的证据。
The influence of side leakage on the onset of Taylor vortices in high-speed journal bearings is studied by observing the effects of varying the eccentricity of, and the axial flow through, an annulus. The apparatus permits of both sharp and smooth entries to the annulus. Flow visualization is achieved by means of aluminium paint pigment suspended in the test fluid. It is shown that both the eccentricity and the axial flow have a marked effect on the critical Taylor number. Evidence is presented for the co-existence of two systems of vortices within the annulus.
