论文摘要
我讨论具有各向异性粗糙度的固体之间界面的流体流动。我表明，对于具有各向异性粗糙度的随机粗糙表面，与各向同性粗糙度相同的相对接触区域的接触区域渗透面积，而Bruggeman有效培养基理论和关键连接理论几乎可以为流体流动性提供了几乎相同的结果。这表明，在大多数情况下，在高放大倍率下观察到的表面粗糙度与流体流动问题（例如静态密封泄漏和流体挤压）无关。
I discuss fluid flow at the interface between solids with anisotropic roughness. I show that for randomly rough surfaces with anisotropic roughness, the contact area percolate at the same relative contact area as for isotropic roughness, and that the Bruggeman effective medium theory and the critical junction theory give nearly the same results for the fluid flow conductivity. This shows that, in most cases, the surface roughness observed at high magnification is irrelevant for fluid flow problems such as the leakage of static seals, and fluid squeeze-out.
