“…For these reasons, in the last ten years, many numerical studies have been published. Aboosaidi et al [8] were among the first to use the CFD to study the air distribution in the cabin of a commercial aircraft without passengers and thermal loads. A similar study was conducted by Mizuno and Warfield [9] who also appraised the concentration of carbon dioxide.…”

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

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.

“…Despite there being some uncertainties in the models, requiring sufficient knowledge of fluid mechanics on the part of a user, and demanding a high capacity computer, CFD has become the most widely used tool for studying air distributions in airliner cabins due to the rapid increase in computer capacity and the development of user-friendly CFD program interfaces. Examples can be found in [9,11,15,19,21,24,25,27,35,37,[44][45][46][47][48][49][50][51][52]. The CFD models used were Reynolds Averaged Navier-Stokes equation (RANS) models and Large Eddy Simulation (LES).…”

“…They used a symmetric boundary condition in the middle of the plane to reduce the computational domain, which contradicted the smoke flow visualization results. Lin et al [45,47] studied airflow and airborne pathogen transport in a section of a twin-aisle aircraft cabin with the RNG k-ε model. The simulation substantially under-predicted the turbulence intensity, especially in and around the breathing zone.…”

Air distributions in commercial airliner cabins are crucial for creating a thermally comfortable and healthy cabin environment. This paper reviewed the methods used in predicting, designing, and analyzing air distributions in the cabins. Two popular methods are experimental measurements and numerical simulations. The experimental measurements have usually been seen as more reliable although they are more expensive and time consuming. Most of the numerical simulations use Computational Fluid Dynamics (CFD) that can provide effectively detailed information. Numerous applications using the two methods can be found in the literature for studying air distributions in aircraft cabin, including investigations on more reliable and accurate models. Our review shows that studies using both experimental measurements and computer simulations are becoming popular. Our review also found that it is necessary to use a full-scale test rig to obtain reliable and high quality experimental data, and that the hybrid CFD models are rather promising for simulating air distributions in airliner cabins.
