title: Air quality inside the passenger compartment of a bus.
abstract: The indoor air quality in the passenger compartment of an intercity bus is studied. A system used for the remotion of the contaminants from the compartment, based on an extraction duct, was projected using a simple, unidimensional flow model with capability to predict the air exchange rate as a function of the vehicle velocity. Some tests using tracer gan methods were performed in a real vehicle with the contaminant remotion system mounted, in order to validate the calculation model and evaluate the performances of the system. A good agreement between the predicted and the experimental results was verified and the obtained air exchange rate was quite reasonable when compared with the former situation, without extraction duct.
