粗糙表面间流体挤出的理论与实验比较

Fluid squeeze-out between rough surfaces: comparison of theory with experiment

B. Lorenz, B. N. J. Persson

摘要:

我们研究的时间依赖性的(平均)之间的界面分离的弹性固体与平面和刚性固体与随机粗糙表面,在流体中挤压在一起。我们使用一个描述流体流动因素的解析理论,基于Ewesson接触力学理论和Bruggeman有效介质理论,计算流体从两个固体接触界面的去除。为了测试这种方法,我们进行了简单的挤出实验。实验结果与理论预测进行了比较。

英文摘要:

We study the time dependency of the (average) interfacial separation between an elastic solid with a flat surface and a rigid solid with a randomly rough surface, squeezed together in a fluid. We use an analytical theory describing the fluid flow factors, based on the Persson contact mechanics theory and the Bruggeman effective medium theory, to calculate the removal of the fluid from the contacting interface of the two solids. In order to test this approach, we have performed simple squeeze-out experiments. The experimental results are compared to the theory predictions.
