摘要
本文用实验方法对管道阻力计算中相邻弯道局部阻力的影响进行了系统的研究,提出了可供实用的弯管相邻影响系数;解释了弯管间局部阻力相邻影响的成因;分析了水利工程中类似的实例。提出为了合理地计及局部阻力的相邻影响,在计算总水头损失时应遵循的算法。
The interaction of local loss between bends in pipeline with different combination is studied experimentally.The formation of the interactive effect is found and the interactive coefficients of different combination of bends for hydraulic calculation are obtained according to the experiment data. It is pointed that the total head loss of pipeline system is the sum of the skin fricition loss, local losses of single bends and the interactive loss of bends.
