DIFFERENCE BETWEEN ARTIFICIAL AND COMMERCIAL PIPES IN TRANSITION ZONE1)

  • 摘要: 管路沿程损失是教学中要讲的内容。其中在过渡粗糙区,人工管和商业管的沿程损失系数存在差异。本文对此差异做了初步分析。从学生对此差异的理解和表面粗糙度的含义两方面探讨了表面粗糙度对此差异的影响。量化探讨表面粗糙度在过渡粗糙区的作用仍是个问题。
    Abstract: Pipe friction is a teaching content in the course of fluid mechanics, in which Darcy friction factors in transition zone obtained by using artificial and commercial pipes are different. The present work shows analyses on the difference at two aspects. One is according to the understanding of students on the problem, and another is from the definition of surface roughness. Both show the surface roughness effect on the phenomenon. It is still necessary to research the quantitative effect of surface roughness on the difference between artificial and commercial pipes in transition zone.
