3D Numerical Modeling of Geyser Formation by Release of Entrapped Air from Horizontal Pipe into Vertical Shaft
TL;DR: Geysers are explosive eruptions of air-water mixture from manholes in drainage systems as mentioned in this paper, when the design capacity of urban storm water drainage systems is exceeded during extreme rainfall.

Modulation of transient pressure by an air pocket in a horizontal pipe with an end orifice
Lin Li,David Z. Zhu +1 more
TL;DR: A numerical analysis of flow processes associated with the pressurization and release of an air pocket in order to study its influence on transient pressure in a horizontal pipe with an end orifice.

Analysis of Pressure Transient Following Rapid Filling of a Vented Horizontal Pipe
Lin Li,David Z. Zhu,Biao Huang +2 more
TL;DR: In this paper, a linearized analytical model was developed to obtain the approximate solutions of the maximum pressure and the characteristics of pressure oscillations caused by the pressurization of trapped air in a horizontal pipe when there is no or insignificant air release.

Numerical investigation of field-scale geysers in a vertical shaft
Taher Chegini,Arturo S. Leon +1 more
TL;DR: In this paper, the authors investigated the mechanisms and the behavior of geysers in dropshafts of stormsewer systems, which are consecutive eruptions of a mixture of gas and liquid.

Impact pressure on an orifice plate by a rising water column driven by an air pocket in a vertical riser.
Yu Qian,David Z. Zhu +1 more
TL;DR: It was found that the initial water column length and the driving pressure, as well as the riser material, have a strong relationship with the peak pressure.

Scaling and trends of hourly precipitation extremes in two different climate zones – Hong Kong and the Netherlands
TL;DR: In this article, the authors investigated hourly precipitation extremes in very long time series from the Hong Kong Observatory and the Netherlands using the 2 m dew point temperature from 4 h before the rainfall event as a measure of near surface absolute humidity.
