- 摘要:
- 摩阻系数的估计是管道系统设计的一个关键，Colebrook-White方程是计算粗糙管紊流状态时摩阻系数的一个典型方法。调研了Colebrook-White水力摩阻系数公式显式化的新进展，将多个显式近似公式进行了计算精度和计算时间的对比，介绍了精确且计算方便的显式Colebrook-White公式，为输气管道工程推荐了实用的摩阻系数计算公式。
Friction coefficient estimation is a key part of gas pipeline system design and Colebrook -White equation is a typical method for computing turbulent flow friction coefficient of rough pipeline. Investigated is new progress of Colebrook -White equation, the noniterative hydraulic friction coefficient formula, compared are calculation accuracy and computation time of several noniterative approximation equations, introduced is the accurate and convenient noniterative Colebrook-White equation and useful friction coefficient calculation formula is recommended for gas pipeline engineering design.
