An Efficient Approach for Nodal Water Demand Estimation in Large-scale Water Distribution Systems

Estimation of Water Demand in Water Distribution Systems Using Particle Swarm Optimization

Abstract: Demand estimation in a water distribution network provides crucial data for monitoring and controlling systems. Because of budgetary and physical constraints, there is a need to estimate water demand from a limited number of sensor measurements. The demand estimation problem is underdetermined because of the limited sensor data and the implicit relationships between nodal demands and ...

Parallel Simulation of Large-scale Water Distribution Systems

This paper describes the development of parallel algorithms for the processing of telemetry data in the specific context of water distribution networks. Today’s increasing complexity of such systems, together with the requirement for smaller discretisation intervals means that the task of simulating large-scale water distribution networks frequently outgrows the computational power of economica...

simulation and experimental studies for prediction mineral scale formation in oil field during mixing of injection and formation water

abstract: mineral scaling in oil and gas production equipment is one of the most important problem that occurs while water injection and it has been recognized to be a major operational problem. the incompatibility between injected and formation waters may result in inorganic scale precipitation in the equipment and reservoir and then reduction of oil production rate and water injection rate. ...

Optimal Node Grouping for Water Distribution System Demand Estimation

Real-time state estimation is defined as the process of calculating the state variable of interest in real time not being directly measured. In a water distribution system (WDS), nodal demands are often considered as the state variable (i.e., unknown variable) and can be estimated using nodal pressures and pipe flow rates measured at sensors installed throughout the system. Nodes are often grou...
