| 摘 要： | 同心环状空间是工程上较常见到的流体流动空间，在此空间中流体流动情况的分析较复杂。工程上对其流动情况的分析常常是引用流体力学中的分析结果，但往往由于对环状空间结构的条件重视不够，引用时很容易出毛病。经过仔细推导分析，指出其应用条件，并有助于对同心环状空间中流体流动时压力损失的分析与计算

| Abstract: | ln engineering,the concentric ring space is an usual flowing space of flu- id . its analysis of flowing condition is very complicated. usually. quoting from the ana- lytical result of Fluid Mechanics . researchers analyze the flowing condition in engineer- ing. But , the quote is often wrong because they don't emphasize enough on the condi- tion in concentric ring structure. The authors point the applying condition after having deduced and analyzed carefully . we hope it helpful to the analysis and calculation of pressure losing which is produced when fluid is flowing through concentric ring space. |
