| 摘 要： | 在管流过程中沿程流体因克服摩擦阻力作功会有能量损失。而在边界形状有突然改变的局部区域如管道相交处，由于过流断面尺寸突变引起主流脱离边界并形成旋涡则会引起局部能量损失。提出管道相交处局部阻力与边界几何条件之间的量化关系，为设计合理的边界几何尺寸提供必要的理论依据。

| Abstract: | The behavior of flowing at intersecting pipes corner is affected by geometry shape of boundary.In this region fluid flowing is subjected to loss of the energy because it is necessary to overcome fricative resistance in pipe flowing.The loss is determined by experimental method usually.This paper tries to express quantitative relation between partial flowing resistance at intersection pipes corner and geometry condition of boundary so that theory basis is provided for designing ideal boundary dimension. |

| Keywords: | pipe geometry shape fluid resistance |
