Manhole Cover Displacement Caused by the Release of Entrapped Air Pockets

Stormwater systems undergoing rapid filling may present a variety of operational problems, one such being the displacement of manhole covers, which can threaten both traffic and pedestrians. This paper, by Jue Wang and Jose Vasconcelos from Auburn University, presents results from an ongoing computational fluid dynamics (CFD) simulation of air pocket release in shafts with limited ventilation at the cover.
