The purpose of this proposed project is to develop a CAVE (Cave Automatic Virtual Environment) program for "Animation of Stereoscopic Experimental Data of Air Flow and Pollutant Transmission in an Aircraft Cabin". From a previous project, the applicant collected a large volume of 3-D air velocity data using an innovative stereoscopic particle imaging velocimetry (SPIV) technology in a 5-row full-size section model of a Boeing 767-300 aircraft cabin. While all 3-D and temporal information exist, it is difficult to interpret and present using conventional graphical means. It is ideal to use CAVE facility consisting of a supercomputer, graphical system, sound system and tracking system to animate the experimental data. Using the CAVE, we can interact with the 3-D velocity flow field data to obtain a better understanding of the airflow distribution inside aircraft cabin and pollutant transmission.

From the CAVE application, the integral airflow patterns in the aircraft cabin can be demonstrated continuously (or at a specific time) using the measurement data. The detailed air distribution in the local areas can be studied, especially those areas with more complicated flow patterns or those areas have more influence on the air quality and health of passengers. The animated visualization tool generated from this study will be very helpful for the design of ventilation system. Meanwhile, the visualization can also enable us to get the Lagrange description of airflow using virtual particles in a temporal sequence, which allows us to track the trajectories of airborne pollutant, and ultimately, to develop new strategies and air distribution systems to improve air quality inside aircraft cabin.
