RISEvaluating the Approximation of the Affinity Laws and Improving the Efficiency Estimate for Variable Speed Pumps
Publisher: American Society of Civil Engineers
Abstract: Affinity laws relate to the characteristics of pumps operating at different speeds, and in a water distribution context, are usually used to predict the pump curve of variable speed pumps (VSPs). VSPs can adjust the pump ...
Correction of the <i>EPANET</i> Inaccuracy in Computing the Efficiency of Variable Speed Pumps
Publisher: American Society of Civil Engineers
Abstract: One attractive possibility for saving energy in water distribution systems is the introduction of variable speed pumps (VSPs). However, to assess the cost effectiveness of using VSPs, a correct estimate of VSP energy ...
Drinking Water Distribution System Network Clustering Using Self-Organizing Map for Real-Time Demand Estimation
Publisher: ASCE
Abstract: Consumer demand estimation is a key step in real-time drinking water system (DWS) modeling used for demand forecasting, optimal operations, and water quality management. Consumer nodes in a DWS are generally clustered to ...
Optimization of Pump Operation Using Rule-Based Controls in EPANET2: New ETTAR Toolkit and Correction of Energy Computation
Publisher: American Society of Civil Engineers
Abstract: The optimization of pump operations has the potential to reduce operational costs, while still maintaining the high level of reliability required of water distribution systems. The hydraulic software EPANET2 toolkit has ...
Multiobjective Design of Water Distribution Networks through the Generation of Pseudofronts in the Hydraulically Feasible Region
Publisher: American Society of Civil Engineers
Abstract: The design of a water distribution network (WDN) is conceptually a multiobjective problem characterized by stringent constraints. Even in its most simple formulation, which requires only the maintenance of minimum pressures, ...
Integrated Approach for Optimizing the Design of Aquifer Storage and Recovery Stormwater Harvesting Schemes Accounting for Externalities and Climate Change
Publisher: American Society of Civil Engineers
