400 - New Insights on Geyser Processes in Sewer Systems Through Laboratory Experimentation and Numerical Modeling

Despite extensive studies conducted on geysers in sewer systems over the past few decades, various unknownspersist regarding the intricate processes that culminate in intense eruption. This paper attempts to provide further insights into geyser processes through the presentation of findings derived from a series of comprehensive laboratory experiments and numerical simulations. The laboratory experiments conducted for this research were characterized by the utilization of cutting-edge wire mesh sensors, specifically designed to measure air fraction at two strategic cross-sections. These novel sensors not only enhanced the precision and accuracy of our measurements but also provided a better understanding of the dynamic interplay of factors influencing geyser behavior. In conjunction with the laboratory tests, we performed three-dimensional computational fluid dynamics simulations to further enrich our understanding of geyser processes. By combining the empirical data obtained from our laboratory experiments with the insights gained from our computational simulations, we aim to provide new perspectives on the intricate mechanisms governing geyser phenomena. This comprehensive approach not only expands the existing knowledge base but also opens avenues for future research and the development of more effective strategies for managing and mitigating the risks associated with intense geyser eruptions in sewer systems.
