Experimental and Numerical Study of Flow and Contaminant Transport Inside an Aircraft Cabin with a Moving Body
This paper presents the preliminary results of an investigation on the effects of a moving body on flow and contaminant transport inside an aircraft cabin.The effects were experimentally studied by using a one-tenth scale-model in a water tank.The flow field across a cabin crosssection induced by the moving body was measured using Particle Image Velocimetry (PIV)technique.The PIV measurements show that the instantaneous flow field can vary significantly,but the mean averaged flow field is symmetric along the vertical centerline of the moving body.A strong downwash flow was also observed along the vertical centerline of the moving body.These experimental data were then used to validate a Computational Fluid Dynamic (CFD) model.The CFD model can effectively capture the mean flow field.Finally the CFD model was used to study contaminant transport under different cabin flow patterns due to a contaminant released from the two sides of a moving body.The maximum contaminant concentrations in a cabin-cross section were found to be similar with different flow patterns.
