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 …

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

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 …

Transient (highly unsteady) air–water two-phase flows and spring-like geysers have been
one of the critical concerns in drainage pipeline systems, which may cause or exacerbate …

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 …

An energy-dissipation model is developed to simulate rapid filling having an entrapped air
pocket within a vertical pipe. Both convective heat transfer and transient wall shear stresses …

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 …

Water conveyance systems are notorious for incurring considerable energy expenditures,
either as losses of gravitational potential energy or as increased electricity consumption …

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 …
