【摘要】 有压管道水力瞬变的正确分析,对工程安全运行影响较大。文章根据瞬变过程中水流流态的变化,采用变摩阻系数,并对阻力项采用二阶近似,提高了水力瞬变分析的精度。更多还原

【Abstract】 Proper analysis on the hydraulic transient in pressure pipeline is important for the safety operation of project. In this paper, the treatment by using a friction factor varying with flow conditions and a second-order approximation of friction term is more accurate for calculating the transient.更多还原
