结果以无量纲形式给出，如在由静止外缸和旋转内缸形成的偏心环中的合成径向力变化的实验研究中获得的，通过该偏心环可以泵送轴向流的油。两个偏心率，0.5和0.9，和三个轴向雷诺数的流体在环空，0，25和50，被认为是流动。结果表明，泰勒涡流的开始对径向合力的大小和方向有显著的影响。的合力和姿态角相比，来自索末菲的径向轴承理论。本调查和文献中提供的临界泰勒数之间的比较。
Results are presented in dimensionless form as obtained in an experimental study of the resultant radial force variation in an eccentric annulus formed by a stationary outer cylinder and a rotating inner cylinder, through which an axial flow of oil may be pumped. Two eccentricity ratios, 0.5 and 0.9, and three axial Reynolds numbers for the flow of the fluid in the annulus, 0, 25, and 50, are considered. It is shown that the onset of Taylor vortex flow has a marked effect on the magnitude and direction of the resultant radial force. The resultant forces and attitude angles are compared with those derived from Sommerfeld’s journal bearing theory. Comparisons are also made between critical Taylor numbers for the present investigation and those available in the literature.
