流体在工业管道中流动沿程阻力计算的研究

Study on calculating frictional resistance of fluid flowing in industrial pipe-line

分析了目前工业管道设计中存在沿程阻力计算不够准确这一现象的原因及由此产生的后果。对于流体力学中计算工业管道内流动沿程阻力系数的柯列勃洛克公式,给出了一种适用于计算机编程的迭代求解方法,并具体运用于空调工程水系统管道比摩阻的计算。

Analysis the causes and results of the phenomenon that calculating of frictional resistance in industrial pipe - line design is not accurate enough. In regard to the Colebrook＇ s formula in hydrodynamics for calculating friction factor of industrial pipe - line, gives an iterative method suitable for computer programming, and specifically applies this method to calculating specific frictional resistance of air conditioning water system pipe - line.
