RESUMO
Este artigo apresenta a aplicação de modelo matemático-computacional de simulação e otimização para localização de fugas. O modelo proposto é fundamentado no acoplamento de um simulador hidráulico baseado no Time Marching Approach - TMA com o algoritmo otimizador de Nelder-Mead e foi aplicado em uma rede de distribuição de água da cidade de Jundiaí-SP. Nos testes realizados ficou claro o funcionamento adequado do modelo apresentado, pois a fuga simulada foi localizada, sendo observado, entretanto, a necessidade de um aprimoramento na localização dos pontos de monitoramento durante a execução da simulação.
ABSTRACT
This work presents a computational model as a new tool for leak localization. The considered model was developed through the coupling of hydraulic simulator based in Time Marching Approach - TMA method with the Nelder-Mead optimization algorithm. The model was applied to a real water distribution network, in the city of Jundiaí, Brazil. In the carried through tests it was clearly the adequate functioning of the presented model, therefore the simulated escape was located, being observed, however, the necessity of an improvement in the localization of the monitor points, during the execution of the simulation.
