Abstract

Experiments were performed in a one-tenth scale, water-based aircraft cabin model to investigate the effect of a moving body on flow and contaminant transport. The flow field and contaminant transport were measured using the Particle Image Velocimetry (PIV) and Planar Laser-Induced Fluorescence (PLIF) techniques, respectively. Measurements were obtained with (ventilation case) and without (baseline case) the cabin environmental control system (ECS). The PIV measurements showed a downwash flow along the vertical centerline of the moving body for the baseline case. The evolution of this flow pattern is profoundly perturbed by the flow from the ECS. Furthermore, a contaminant originating from the moving body is observed to convect to higher vertical locations in the presence of ventilation.
