RÉSUMÉ

Air conditioning in large body aircraft is a very important and delicate task. Due to the complex cabin geometry, it is difficult to obtain an equally distributed low-speed airflow with high air exchange rates. Experimental data of the A/C flow have to be provided for development or verification of computational fluid dynamics codes (CFD) that can be used for optimization. The technique described in this publication uses soap bubbles filled with helium for visualization and particle tracking software for image analysis. Time averaging of long image sequences is used to produce air velocity vector plots and vorticity contour plots. The complex A/C flow shows rotational flow areas and proves that air velocities are well in the range of the aircraft specifications. Qualitative comparison between experiment and CFD calculation is reasonable and encourages the use of CFD for cabin design to optimize the A/C flow.
