N2 - Enhanced soiling on the surfaces around the nozzles due to particle deposition is a problem to the cabin environment in commercial airliners, which is more serious due to the severe outdoor air pollution and flight delays in China. The particles inside aircraft cabin origin from both outdoor and in-cabin sources. Measurements on multiple commercial flights were conducted to obtain particle emission rates from in-cabin sources. With the measured data, this investigation proposed a method by using a CFD model for predicting the accumulation of the particles deposited around the nozzles of an airplane, combining with its historical flight routes and outdoor particle concentrations of the cities where the airplane stayed. The method proposed in this study can be used for any airplanes of an airliner to predict the accumulation of the particles deposited around the nozzles over a period time of operation.
