“…The constructal literature is expanding rapidly in the domain of tree-shaped designs for conduction, [31][32][33][34][35][36] fluid flow, [37][38][39][40][41][42][43][44][45] and convective heat transfer. [46][47][48][49][50] A central feature of these designs is the notion that when channels bifurcate or coalesce their diameters should change by certain factors, so that the overall flow through the architecture is facilitated.…”

This is a review of the theoretical and applied progress made based on the Constructal law of design and evolution in nature, with emphasis on the last decade. The Constructal law is the law of physics that accounts for the natural tendency of all flow systems (animate and inanimate) to change into configurations that offer progressively greater flow access over time. The progress made with the Constructal law covers the broadest range of science, from heat and fluid flow and geophysics, to animal design, technology evolution, and social organization (economics, government). This review presents the state of this fast growing field, and draws attention to newly opened directions for original research. The Constructal law places the concepts of life, design, and evolution in physics.

“…Optimization techniques have been applied to the design (or more specifically, the dimensioning) of water networks for decades (see Bieupoude et al, 2012, andDe Corte andSörensen, 2013, for overviews). A widely applied approach is that of genetic algorithms (GAs) (Holland, 1975;Goldberg, 1989) and other members of the overarching family of evolutionary algorithms (EAs) (Maier et al, 2014).…”

Abstract. Genetic algorithms can be a powerful tool for the automated design of optimal drinking water distribution networks. Fast convergence of such algorithms is a crucial factor for successful practical implementation at the drinking water utility level. In this technical note, we therefore investigate the performance of a suite of genetic variators that was tailored to the optimization of a least-cost network design. Different combinations of the variators are tested in terms of convergence rate and the robustness of the results during optimization of the real-world drinking water distribution network of Sittard, the Netherlands. The variator configurations that reproducibly reach the furthest convergence after 105 function evaluations are reported. In the future these may aid in dealing with the computational challenges of optimizing real-world networks.

“…In the system, where the effect of the pressure is so high, it is essential to apply the most appropriate pressure control system to reduce failure rates, reduce leaks and thus reduce operating and maintenance costs. In studies conducted in the literature, it was seen that various studies have been carried out to reduce the effect of pressure in failures and leakage management (Fanner et al 2007;Fanner & Lambert 2009;Nazif et al 2010;Wu et al 2010;Gomes et al 2011;Bieupoude et al 2012;Karadirek et al 2012;Dai & Li 2014;Schwaller & van Zyl 2015;Creaco et al 2016;Martínez-Codina et al 2016;Vicente et al 2016;Giustolisi et al 2017). On the other hand, besides the benefits of pressure control management, components such as automation system, room construction, device and equipment selection-placement and monitoring of data are important costs and it was emphasized that detailed analysis and evaluation should be performed before PM is applied (Charalambous & Kanellopoulou 2010).…”

Pressure has an important effect on the occurrence of failures/leaks in water distribution systems (WDSs) or the change of leakage in existing leakages. For this reason, monitoring the pressure is important especially for analyzing the changes in the day and night, determining the fluctuations and applying pressure management (PM) to ensure normal operating conditions. In this study, the effect of pressure on water losses and minimum night flow (MNF) was carried out according to the Fixed and Varied Area Discharge (FAVAD) approach which allows the amount of leakage to be calculated based on the change in pressure and field tests. The minimum flow rate and potential leakage were determined under the network operating conditions before the pressure control in region. Then, considering the features of the region, pressure was reduced with the pressure control system and MNFs and leaks were monitored. By reducing the pressure from 9.10 bar to 3.2 bar in the region, the MNF rate was reduced from 6.95 l/s to 3.29 l/s. The daily water savings in the system inlet volume is 78.44 m3/day and the annual saving is 28,624 m3 /year. The results obtained are very important for practitioners in terms of implementing PM in the field.
