Abstract: Stormwater geysers are commonly observed as explosive releases of air-water mixtures from municipal systems, which can cause property damages and human safety concerns. In Edmonton, Alberta, Canada, a number of geyser ...

Abstract: Air in the headspace of sewer laterals can be driven by the flowing sewage as well as air pressure. In this study, the openings on manholes for air flow are approximated as a thin continuous slot at the laterals. In this ...

Abstract: Geysers can occur in storm sewer systems during heavy storm events, leading to public safety concerns. In this study, a physical model as well as a transient three-dimensional computational fluid dynamic model were used ...
