Contaminant Distribution

Indoor air quality studies are very important as they allow designers to verify that a comfortable and healthy environment is being provided before it is physically constructed. It can be especially important on the closed confines such as a commercial aircraft which may carry a high density of people from various parts of the world. In this study, 3-D contaminant dispersion simulation within an aircraft is conducted by using Finite Volume Methods. Effects of two types of air distribution systems on contaminant dispersion are analyzed. The preliminary results show that the Under Floor Air Distribution system performs better in the overall air quality provided to the passengers of the aircraft than the Ceiling Air Distribution system.
