“…The total heat load for each human simulator was 83 W. Air was supplied at the ceiling level from two linear slot diffusers and exhausted from the outlets at the floor level on the side walls. A tracer gas, sulfur hexafluoride (SF 6 ), was used to simulate a gaseous contaminant. Non-evaporative, monodispersed Di-Ethyl-Hexyl-Sebacat (DEHS) particles were also generated to simulate a particulate contaminant.…”

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.

“…More recently, Lin et al [6] applied a Particle Image Velocimetry (PIV) system to measure air velocity field in a generic empty cabin and used the data to validate the numerical results simulated by large eddy simulation (LES). The details of the airflow field and turbulence energy spectrum were analyzed.…”

“…Laboratory experiment seems more affordable and thermo-fluid boundary conditions are easier to control with state-of-the-art experimental facilities. A lot of laboratory measurements of airflow and/or contaminant transport were performed on empty cabin mockups without considering the effects of occupancy [13][14][15] . Singh et al 16 used heated cylinders to approximate the effects of passengers and studied the airflow pattern inside an aircraft cabin.…”

Quantifying the airflow field in building room or vehicle cabin indoor space is crucial for creating a thermal comfortable and healthy indoor environment. Airflow field measurement can provide quantitative information of indoor air distribution and local air velocity around occupants or passengers, which has strong relationship with the ventilation effectiveness, the pollutant transportation and the energy conservation in a building or a vehicle. However, the airflow field in indoor environment is normally characterized by high turbulent level and unsteady due to relatively low air velocity from the diffuser, thermal plume of heat source and unsteady perturbation of occupants' behavior. Generally, it is very difficult to conduct accurate and detailed measurement of such a complex turbulent flow field with point-wise anemometry.
