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 …

When pipelines are rapidly filled, dynamic and sometimes dramatic air–water interactions
often occur. These air–water interactions, along with their associated pressure and …

One potential problem affecting below-grade storm-water storage tunnels is the occurrence
of geysering, which is defined as the return of conveyed water to grade. Most investigations …

Storm sewer systems may experience storm geysers, raising concerns about public safety. A
thorough understanding of the influential factors of the geysers is essential yet insufficiently …

Geysers are explosive eruptions of air-water mixture from manholes in drainage systems.
When the design capacity of storm water drainage systems is exceeded during heavy …

Uncontrolled air pocket release from water-filled shafts can lead to geysering in stormwater
systems. Such occurrences are deleterious from public health and environmental …

Transient flow caused by air expulsion is investigated. Earlier experimental studies involved
the horizontal or horizontal–vertical pipe cases, or the vertical pipe case with relatively less …

This paper reports a laboratory study on violent geysers in a vertical pipe. Each geyser
produced consists of a few consecutive violent eruptions within a time frame of a few …

Air expulsion from an end-of-pipe orifice in a rapidly filling horizontal pipe is investigated
experimentally and analytically in order to more completely characterize the system's …
