Modeling and Simulation of a Hydraulic Network for Leak Diagnosis

“…The set of Equations (13)-(29) obtained in the previous section is solved in MATLAB R using the nonlinear optimization method called "trust region", whose purpose is to solve a system of equations f (x) = 0 in order to find the optimal solution through an iterative process minimizing f (x) 2 . The efficiency of this numerical method is due to its rapid convergence [21]; in fact, it only takes 3-5 s to simulate, on a PC with a Core i5 processor, 24 h of running time.…”

“…Leaks have serious consequences such as environmental pollution, economic losses and human deaths from hydrocarbon explosions. Leaks occur more frequently in worn pipes, pipes with low maintenance, pipe joints or in some accessories such as elbows and valves, among others [2].…”

Two-Leak Isolation in Water Distribution Networks Based on k-NN and Linear Discriminant Classifiers

“…For instance, fault-sensitive-based, model-based and transient-based techniques have been reported considering either single-or multi-leak problems [4][5][6][7][8][9] for both single and branched pipelines. Moreover, to address the leak diagnosis problem in a WDN, these techniques are not generally suitable and other strategies have also been proposed, but they are based on artificial intelligence (AI) and data-driven approaches, as in [10][11][12][13][14], to mention a few recent works. Other approaches that have been used for a long time, such as the acoustic-based approach, identify the area where the leak is occurring on the basis of changes in the noise generated by measurements coming from the WDN [15][16][17].…”
