|Elevator Shaft Vapor Intrusion Modeling using Computational Fluid Dynamics|
|Keywords: CFD, modeling, vapor|
|Airflow within an elevator shaft that had been contaminated with naphthalene vapor from an old gasoline leak at a nearby filling station became the source of a challenging study. Naphthalene vapor leaking from the ground under the elevator shaft was believed to be leaking into the apartment complex corridors at levels that exceed long-term exposure limits and threatened to shut down occupancy of the complex. This study used computational fluid dynamics to model the vapor intrusion into the apartment corridors during periods of elevator inactivity when temperature stratification takes place in the shaft and also due to the pumping action of the elevator as it moves up and down through the shaft during periods of high activity.|
