An experimental study of ventilation effectiveness and pollutant transmission in an aircraft cabin

Experiments were conducted in the mockup of a Boeing aircraft cabin section located in the BESS(Bioenvironmental Engineering Structure Systems) lab at the University of Illinois at Urbana-Champaign. The objectives of this experiment study included characterizing air distribution using VPTV (velometric particle tracking velocimetry) technique and determining local mean age of air in the ventilated airspaces and ventilation effectiveness using a tracer gas method to evaluate the performance of ventilation systems in removing airborne pollutants. The results obtained can be used for improving ventilation design and implementing air-cleaning strategies..
