Initiation of Air Trapping between Two Manholes in a Stormwater Conduit

Abdulmuttalib M. Lokhandwala, Yichen Tao, Vitor G. Geller, Daniel B. Wright et autres

New analysis methods are developed for evaluating the initiation of air trapping in a closed stormwater conduit between two manholes. Identifying conduits and flow conditions at risk for air trapping is a necessary precursor to identifying the likelihood of damaging adverse multiphase …

Investigation of Air Pressurization during the Filling of Complex Pipe Networks

Vitor G. Geller, Yichen Tao, Abdulmuttalib M. Lokhandwala, Jose G. Vasconcelos et autres

Drinking water systems (DWS) frequently undergo maintenance operations in which emptying and subsequent filling (i.e., priming) operations are necessary. Air pressurization is an undesired effect during priming operations, but there are limited studies that have focused on this problem. The various interactions …

Evaluating SWMM Modeling Performance for Rapid Flows on Tunnels with Geometric Discontinuities

Vitor G. Geller, Yichen Tao, Abdulmuttalib M. Lokhandwala, José G. Vasconcelos et autres

The EPA’s Storm Water Management Model (SWMM) has been applied across the globe for citywide stormwater modeling due to its robustness and versatility. Recent research indicated that SWMM, with proper setup, can be applied in the description of more dynamic flow conditions, …
