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 …

With the development of urban areas, many municipalities are facing issues where the flow
velocity in their sewer systems is relatively high at various locations. This is because of …

A pump− pipeline experiment platform is designed and built for exploring the dynamic flows
in a pipe-conveying fluid with entrapped air, and a corresponding CFD simulation is …

This paper presents results from seven experimental facilities on the co-current flow of air
and water in downward sloping pipes. As a function of the air flow rate, pipe diameter and …

Deep storm-water storage tunnels may undergo pressurization during intense rain events. In
the process, air pockets may become entrapped and pressurized, causing significant flow …

The effect of air pocket during rapid filling of partially full pipe with dead end is investigated
experimentally. The air–water flow patterns are observed with a high-speed camera …

The behaviour of elongated air pockets in downward sloping pipes is investigated. The
observed flow regimes in co-current air–water flow in downward sloping pipes are …

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 …

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 …
