Abstract: Unexpected, unknown or unused side pipe branches, termed dead-end side branches in this study, commonly exist in water pipe systems because of incorrect device installations or illegal connections. These connections are ...

Abstract: Unsteady friction and its modeling have been widely studied in transient pipe flows for its influences and modification effect on pressure waves. Such a feature is of great importance particularly in pipe systems where the ...

Abstract: Partial blockages commonly exist in pressurized pipeline systems, and the rapid remediation of such faults is required to reduce the wastage of energy as well as to maintain the serviceability of the pipe network. Numerous ...

Abstract: This paper investigates the importance of pipe system scale—specifically pipe length and diameter—on unsteady friction in pipe transients. A dimensionless analysis is conducted for the one-dimensional (1D) water-hammer ...

Abstract: In the last two decades, energy dissipation in unsteady-state pressurized pipe flow has been examined by various authors, where the instantaneous wall shear stress is split into a quasi-steady and an unsteady shear stress ...

Abstract: Blockages in urban water supply systems are commonly formed from various complicated physical, chemical, and biological processes; thus, they usually constrict randomly and nonuniformly along their lengths. Although the ...

Abstract: Partial blockages commonly exist in water pipelines due to various physical, chemical, and biological processes, including sediment, corrosion, and biofilm. The formed blockages can result in low flowing capacity, additional ...
