Análise do golpe de aríete: Estudo de caso para a adutora de água bruta do sistema Capim Branco em Uberlândia/MG

Abstract

Water transmission pipelines are critical infrastructures in water supply systems, and their efficient and safe management is essential for the well-being of dependent communities. In this context, the study of water hammer phenomena becomes indispensable, as it can cause significant impacts on pipelines, potentially compromising the entire supply system. This study aimed to analyze water hammer effects in the raw water pipeline from the Capim Branco reservoir, utilizing the ALLIEVI software for simulation and system performance evaluation. The methodology involved the characterization of the pipeline system, software modeling, and the analysis of different scenarios, considering the absence and presence of mitigating devices such as air valves, one-way surge tanks, and hydropneumatic reservoirs. The results indicated that, without protective devices, the pipeline faced significant risks of cavitation and structural damage. Among the devices evaluated, the hydropneumatic reservoir was the most effective in mitigating pressure surges, whereas air valves showed limited impact. It is concluded that the combined use of mitigation devices is essential to ensure the safety and operational efficiency of large-scale pipeline systems.
