Filling and emptying processes are common maneuvers while operating, controlling and
managing water pipeline systems. Currently, these operations are executed following …

Air can be entrapped in water and wastewater systems under a variety of conditions, and if
such air is not managed properly, it can impose considerable operational penalties. To …

Transient simulation is very important to protect the water supply pipeline system from
extreme pressures. In order to numerically simulate the transient response in a variable …

In urban stormwater systems, a rapid increase in water inflow can cause the entrapment of
air pockets and subsequent ejection of air/water mixture, commonly known as storm …

An air pocket's behaviour inside of a pipeline during transient conditions is of great
importance due to its effect on the safety of the hydraulic system and the complexity of …

Stormwater systems, while designed to operate in free surface flow conditions, can undergo
transition to pressurized flows during rapid filling conditions where inflows exceed the …

ABSTRACT A 3D computational fluid dynamics model based on a volume of fluid (VOF)
approach is presented to simulate air-water interactions and transient pressures in T …

Deep storage tunnels are an alternative to mitigate combined sewer overflows, but they may
develop transient flow problems during rapid filling conditions. Such issues include …

Surges caused by the sudden compression of entrapped air pockets are a source of serious
issues in various hydraulic conveyance systems. Such surges may appear during rapid …

Storm water and combined sewer systems are subject to rapid filling during intense rainfall
events. These large-sized systems require a significant amount of air to be vented during …
