Abstract

Abstract The effects of interference of pressure waves in simple piping systems were studied. A freeware computer code Allievi developed at the University of Valencia was used to simulate dynamic waveforms in simple and complex networks. The tests were carried out according to three scenarios. No pressure increases significantly exceeding the Joukowsky pressure in simple cases were noticed. When the effects of the simultaneous closing of three valves located at the three pressure reservoirs with pipes of the same diameter connected at "Y" junction were tested, it was shown that wave interference (between primary and reflected waves) is influenced strongly by the length of the analyzed pipes. Additionally, when a change of diameter was assumed at the "Y" junction, secondary waves appear, which are responsible for increased pressure in this type of the system (even when the lengths of the lines are identical). Water supply pipe systems are subject to cyclical loads and wave interference of similar types even during standard operations, that’s why the understanding of this issue is crucial to effectively protect the systems from the risk of possible cracks, bursts, and leaks.

液压管路系统阀门同时关闭过程中波动相互作用的初步研究

摘要研究了简单管道系统中压力波干涉的影响。在瓦伦西亚大学，Allievi开发了一个免费的计算机代码，用来模拟简单和复杂网络中的动态波形。试验是根据三种情况进行的。在简单的情况下，没有发现明显超过Joukowsky压力的压力增加。同时关闭位于三个压力储层上的三个阀门，并以“Y”型连接相同直径的管道进行测试，结果表明，波干涉(主波和反射波之间的干涉)受分析管道长度的强烈影响。此外，当假设在“Y”型连接处直径发生变化时，会出现二次波，这是导致这种类型系统压力增加的原因(即使线的长度相同)。即使在标准操作期间，供水管道系统也会受到周期性载荷和类似类型的波干扰，这就是为什么了解这个问题对于有效保护系统免受可能出现的裂缝、爆裂和泄漏的风险至关重要。

期刊介绍： Water Resources Management is an international, multidisciplinary forum for the publication of original contributions and the exchange of knowledge and experience on the management of water resources. In particular, the journal publishes contributions on water resources assessment, development, conservation and control, emphasizing policies and strategies. Contributions examine planning and design of water resource systems, and operation, maintenance and administration of water resource systems. Coverage extends to these closely related topics: water demand and consumption; applied surface and groundwater hydrology; water management techniques; simulation and modelling of water resource systems; forecasting and control of quantity and quality of water; economic and social aspects of water use; legislation and water resources protection. Water Resources Management is supported scientifically by the European Water Resources Association, a scientific and technical nonprofit-making European association.
