Abstract

This paper presents an experimental investigation into lift generation during the tangential motion of an inclined surface over a compressible porous layer, focusing on an exceptionally slow sliding speed, a condition that has not been considered in previous studies. Specifically, we validated Pascovici's one-dimensional lubrication model for an inclined slider under the above condition. Additionally, we explore the use of woven fibrous material for soft porous lubrication, broadening the range of media for future studies.

高多孔介质流体动力轴承中的压力评估
本文介绍了对倾斜表面在可压缩多孔层上切向运动过程中升力产生的实验研究,重点关注超低滑动速度,这是以往研究中未考虑过的情况。具体而言,我们验证了 Pascovici 的一维润滑模型,该模型适用于上述条件下的倾斜滑块。此外,我们还探索了使用编织纤维材料进行软多孔润滑的方法,为今后的研究拓宽了介质范围。
