摘要
本文从辐射管非均匀集水的水力特性出发,在对大量模拟试验数据进行系统分析的基础上,提出了关于辐射管有效长度的概念,并经回归分析,得出了辐射管有效长度的经验公式。最后,用模拟试验与生产性试验结果对该公式进行验证,计算值与实测值之间的偏差大多数在±8.33%以内,能满足工程设计的精度要求。
Concept of effective length of radial collector pipe is brought forward in this paper by starting with the hydraulic characteristics of non-uniformly collected water of radial collector pipe and conducting systematic analyses on many data of simulation tests. The empirical formula for calculating the effective length is acquired through regression analysis, verified by comparison between results of simulation tests and productive tests, the deviations of calculated values from measured values are within the range of±8.33%, which meet the precision requirements of engineering design.
