本文为饮用水分配网络中发生的水力瞬变如何调动附着在管壁上的物质,从而导致不可接受的水质和客户不满提供了新的见解。结果报告从广泛的,有代表性的,物理实验涵盖了广泛的可重复的快速加速和减速液压条件。新颖的时间同步分析表明,动员总是发生在暂态的第一次动态浪涌;然而,在控制移动的物理过程的差异被观察到两组瞬态类型的研究。提出了一个估计动员力的函数,并将其应用于所进行的物理实验。该研究为识别和理解瞬变期间引起的机制和力量提供了重要见解,这对于确保在运行分配系统中提供安全饮用水至关重要。
This paper provides new insight into how the hydraulic transients that occur within drinking water distribution networks can mobilise material adhered to the pipe wall and hence cause unacceptable water quality and customer dissatisfaction. Results are reported from extensive, representative, physical experiments covering a wide range of repeatable rapidly accelerating and decelerating hydraulic conditions. Novel time synchronous analysis shows that mobilisation always occurs in the first dynamic surge of the transient; however, differences in the physical processes that govern mobilisation were observed between the two groups of transient type studied. A function to estimate the mobilising force is proposed and applied to the physical experiments performed. The research provides important insights for identifying and understanding the mechanisms and forces induced during transients, vital for ensuring the supply of safe drinking water in operational distribution systems.
