Numerical Investigation of the Physical Mechanisms behind Geysers in Storm Sewer Systems: A Slug Analysis Based on a Computational Study of Geyser Eruptions
Publication: World Environmental and Water Resources Congress 2024
ABSTRACT
The purpose of this study is to investigate the dynamics of geyser eruptions using three-dimensional computational fluid dynamics in an inverted Tee pipe. The research focuses on assessing the interaction of air-water phases, using numerical simulations based on a finite volume approach in OpenFoam. The geometry of the design includes horizontal 6-in. pipes and a drop shaft along with an air intake. Preliminary results indicate that, during the eruption condition, water and air superficial Reynolds numbers exceed 105 in the horizontal pipe. Furthermore, this study examines how pressure changes influence slug formation and growth in horizontal pipes, as well as the intensities of geysers. Based on our findings, as a result of higher pressure within the slug area, a larger slug causes more intense eruptions. The results of this study provide valuable insight into the fluid dynamics of geyser eruptions in storm sewer systems.
