Optimal design of air chambers in water pumping systems by multiobjective genetic algorithms
ABSTRACT Protection devices can be used to protect a water transmission system in a hydraulic transient state, such as the Air Chamber, which can dampen both positive and negative pressure waves. This study proposes an optimal sizing of air chambers through genetic algorithms NSGA-II and NSGA-III co...

| Summary: | ABSTRACT Protection devices can be used to protect a water transmission system in a hydraulic transient state, such as the Air Chamber, which can dampen both positive and negative pressure waves. This study proposes an optimal sizing of air chambers through genetic algorithms NSGA-II and NSGA-III combined with air valves in the pipeline. A real-life transmission system located in Brasilia-Brazil was simulated and analyzed. The results indicate the effectiveness of both algorithms in seeking optimal solutions and show the influence of guaranteeing safe minimum pressures in decision-making. We generate a Pareto front and highlight the best solutions. |
