Mixed flows in storm water systems (SWSs) generate a set of complex phenomena that are
difficult to capture in modeling. Shock-fitting and shock-capturing techniques are the two …

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 …

The pressure surges for water filling in deep stormwater storage tunnels (DSSTs) with
entrapped air-pockets seriously threaten the safety of pipeline structures and even lead to …

This work considers the behaviour of air inside pipes when the air is expelled through air
valves. Generally, the air shows isothermal behaviour. Nevertheless, when the transient is …

The existing one-dimensional model is inadequate in predicting the dynamic interactions
between hydraulic transients and inline air pockets in water pipelines, leading to …

The paper proposes a novel methodology to locate and quantify entrapped air pockets
created during pipe-filling events often found in intermittent water supply systems. Different …

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 …

Entrapped air pockets are linked to various operational issues in closed pipe flows. Tracking
of entrapped air pockets is a relevant task in numerical simulation of hydraulic systems …

Entrapped air blocking the flow in pipeline systems is a common cause of increased
pumping costs. At present, air is generally removed via valves or pipeline excavation and …

Flow regime transition is observed in closed conduit when there is a transition between free
surface and pressurized flows. This condition is often observed in stormwater storage …
