Special Issue Information

Dear Colleagues,

Water distribution systems (WDSs) provide consumers access to safe and sufficient drinking water, making them a vital infrastructure component. This involves both the development of new systems and the upgrading and expansion of existing ones to address increasing water demands. Optimization is one of the most effective tools used, and it comes in the form of different approaches (e.g., gradient-based approaches, metaheuristic techniques, etc.) for designing and operating these important systems. Safe and optimal design and operation of WDSs is a challenging task that requires solving numerous simultaneous nonlinear equations while optimizing components' sizes, locations, and operational statuses. The complexity of this task increases when additional requirements, such as water quality and objectives beyond cost-effectiveness, like potential fire damage, are considered. Furthermore, real-life factors such as uncertainty and phased construction add to the intricacy of the optimization problem.

Within the context described above, this Special Issue presents the latest developments and approaches for the sustainable management of WDSs. The scope of the Special Issue is broad, as it includes different types of solutions for managing WDSs, the development of new algorithms for optimal design and operational statuses of components (e.g., pipes, pumps, tanks, and valves) for deterministic and probabilistic conditions, novel advanced network simulation procedures, and machine learning-based frameworks focused on the dynamic performance of WDSs, e.g., identifying contamination sources, predicting water pressure and demands at nodes, life-cycle assessment, sensitivity analysis, etc. Both theoretical developments and practical applications of WDSs are particularly welcomed.

This paper investigates air–water interactions during a controlled filling process of an actual water pipeline using a two-dimensional Computational Fluid Dynamics (CFD) model. The main objectives are to understand the dynamic interaction of these fluids through water inflow patterns, pressure pulses, and air-pocket dynamics based on contours. This study uses an existing cast iron pipeline 485 m in length, a nominal diameter of 400 mm, and an air valve with a nominal diameter of 50 mm. The methodology of this CFD model includes the Partial Volume of Fluid (pVoF) method for air–water interface tracking, a turbulence model, mesh sensitivity and numerical validation with pressure and velocity measurements. Results highlight the gradual pressurization of pipelines and air pocket behavior at critical points and show the thermodynamic interaction concerning heat transfer between gas and liquid. This study advances the application of CFD in actual water pipelines, offering a novel approach to air pocket management. Full article
