关于管道内壁表面特性与流体摩阻关系的讨论

A Discussion on the Relation between the Characteristics of Pipeline Internal Wall Surface and the Resistance of Fluid

根据统计力学的研究成果,分析了流体沿壁面的滑移问题。指出:管壁润湿特性与滑移无直接关系,决定性影响因素是Knudsen准则。并对有关的减阻实验提出了建议。

Based on the researching results of statistical mechanics, this paper analyses the problem of fluid sliding along the pipe wall. It points out that there is no direct relation between the lubricating characteristics of pipe wall and the sliding and that the desicive factor for interference is the Knudsen Standard. It also make the suggestion on the relative practices for reducing resistance.
