The study of airflow and contaminant transport in airliner cabins is very important for creating a comfortable and healthy environment. This paper shows the results of such a study by conducting experimental measurements and numerical simulations of airflow and contaminant transport in a section of half occupied, twin-aisle cabin mockup. The air velocity and air temperature were measured by ultrasonic and omni-directional anemometers. A gaseous contaminant was simulated by a tracer gas, sulfur hexafluoride or SF 6 , and measured by a photoacoustic multi-gas analyzer. A particulate contaminant was simulated by 0.7 μm Di-Ethyl-HexylSebacat (DEHS) particles and measured by an optical particle sizer. The numerical simulations used the Reynolds averaged Navier-Stokes equations based on the RNG k-ε model to solve the air velocity, air temperature, and gas contaminant concentration; and employed a Lagrangian method to model the particle transport. The numerical results quantitatively agreed with the experimental data while some remarkable differences exist in airflow distributions. Both the experimental measurements and computer simulations were not free from errors. A complete and accurate validation for a complicated cabin environment is challenging and difficult.

“…In the present analysis, k -ε turbulent model in the RNG form is adopted, because it was broadly validated by other authors in different enclosed environments [13,16,[18][19][20] and, moreover, for the case analyzed in the present paper, to the best of our knowledge, experimental data, to validate the model, do not exist.…”

International audienceThe objective of the present work is the numerical simulation of the thermal and fluid dynamic field in the cabin of an executive aircraft. A transient analysis is conducted on three and two-dimensional models of an executive aircraft cabin and a comparison of the two approaches is provided. In the model, a global thermal conductance was considered to take into account both the external environment and the fuselage material. The results, provided in terms of graphs and contours, refer to the three and two-dimensional models with inclined top inlets with respect to the vertical direction of an angle of 45°. A good qualitative agreement between the results of the two and three dimensional models is detected

“…However, for the investigated type of flow problem this is not the case. Zhang et al (2007) show that the performance of specific turbulence models can depend on the type of flow problem for which it is applied. Following the comparison, the standard k-ε model was chosen as turbulence model for the further evaluations.…”
