Résumé

The aims of the study were to: 1/ develop a CFD (computational fluid dynamics) model for an aircraft cabin section and 2/ determine the effects of occupant heat loads on the numerical results. The computations were performed using commercial software for an airplane fuselage section (hereafter, called cabin). Conditioned air entered the cabin through a three-slot diffuser located on the ceiling, flowed along the aisle, and exited through a return located on the floor on both sides along the cabin. All walls and ceilings were insulated. The paper presents velocity, temperature, and turbulence kinetic energy profiles at two cross-sectional planes of the cabin. Good agreement between the numerical simulation results and experimental data was achieved.
