Abstract

Abstract: In order to obtain the distribution and influencing range of gas pollutants in cabin released by single point source,the complete economy class cabin model of B737 -700 with 20 rows of seats is established and the diffusion process of gas pollutants under the influence of cabin AC system is simulated by Fluent. Comparing the difference among pollutant distribution with pollutant source separately locating on sidewall, on luggage rack and in seat, the relation between pollutant distribution range exceeding the threshold of dangerous concentration and the releasing rate of pollutant source is analyzed. Simulation results show that the same pollutants released at different locations have the similar influencing range under the action of AC system. The pollutant influencing range exponentially increases with the releasing rate.

Key words: aircraft cabin, pollutant distribution, pollutant releasing rate, Fluent
