Velocity and turbulence intensity profiles of airflow inside a section of Boeing 737 aircraft cabin were measured using PIV technique. The purpose of the measurement was to provide experimental data for the validation of CFD models being developed for evaluation of air quality and thermal comfort. The test section is approximately 5.6 m long, 2.8 m high and 3.4 m wide, holding 18 passenger seats distributed in 3 rows. A thermal manikin that accurately reproduces the geometry and heat generation of a human being was seated in one of the seats to simulate the human body.
This paper reports the results of thermal comfort and indoor air quality studies in forty-three flights with a duration of more than one hour. The measurements were performed continuously during the whole flight (from the departure gate to the arrival gate) and the parameters monitored were temperature, relative humidity and carbon dioxide concentration. The results were then compared with the ASHRAE Standards for the thermal and indoor air quality.
