Transients in hydraulic systems are normally simulated by one-dimensional (1D) method of characteristics (MOC). When local three-dimensional (3D) flow patterns have crucial impacts on the system characteristics, 3D computational fluid dynamics (CFD) simulation should be incorporated. Since simulating an entire long CFD is unrealistic, we proposed several 1D-3D coupled methods. However, methods ...

The system’s excessive pressure management after zoning is essential for improving the existing water supply operation efficiency. Our original research proves that control reduces leaks in network, increasing reliability level of internal and external networks saving energy consumed pumping systems. In recent years, 243 regulating valves (PRV) have been installed 97 zones expanded network Yere...

The Schur complement domain decomposition method is used for solution of large linear systems. The algorithm is based on the subdivision of the domain into smaller ones and the solution of those subdomains independently. Regarding water distribution systems modeling, the hydraulic simulation could be formulated as a sequence of systems of linear equations. Therefore, this paper utilizes the dom...

The increased systems complexity and performance request for electro-hydraulic applications, ask for more performing electronic systems and control functions. The new powerful microcontrollers and efficient cross compilers, encourage the floating point mathematics usage in the software control routines, useful to directly reuse the routines generated by the simulation tools, despite the lack of...
