    Abstract
  • B737NG cabin model was taken as object, and CFD method was used under the working condition of no passenger to analyze the distributions of air velocity, temperature, formaldehyde concentration and carbon dioxide concentration in aircraft cabin under four kinds of air supply modes, named ceiling air supply mode, luggage rack air supply mode, ceiling and luggage rack air supply mode, and ceiling and personal air supply port air supply mode.Research result shows that under the third and fourth air supply modes, the distributions of air velocity in cabin are uniform, and air velocity near to passenger seat is about 0.2 m·s-1.Under the fourth air supply mode, the distribution of temperature in cabin is most uniform, and the temperature increases gradually to 296 K from air supply port to passenger seat.Under the third and fourth air supply modes, the formaldehyde concentration in cabin is lower.Under four air supply modes, the carbon dioxide concentration in cabin is in the standard range.Among four kinds of air supply modes, ceiling and personal air supply port air supply mode can make the distributions of air velocity and temperature more uniform, remove air pollutants more effectively, and provide better air quality.
