Abstract:Two methods for steady-state analysis of water distribution networks (WDNs) were evaluated in this paper: Global Gradient Algorithm (GGA) and inverse matrix method (IMM). Both methodologies are based on the solution of nonlinear system of equations formed by mass and energy balances within a WDN. A number of WDNs were solved using both methods. Results showed that GGA solves the WDNs in around 70 to 75% less number of iterations than IMM. Besides, single GGA solution of a WDN takes less time compared to IMM so… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
