Abstract:
Accurate prediction of particle deposition in airliner cabin is important to estimate exposure risk of occupants to infectious diseases. This investigation simulated airflow field, particle dispersion and deposition in a half-occupied four-row cabin mockup using a Detached-Eddy Simulation (DES) model with a modified Lagrangian method. Three types of particles with diameters of 0.7, 10 and 100 μm were studied that represent different particle dispersion and deposition processes. This study tested two flow scenarios: one is a breathing case in which particles were released from an index occupant with very small inertial force; and the other is a coughing case in which the particles were released by a high momentum jet flow. This study found that the DES model with the modified Lagrangian method can predict reasonably good results for air velocity, particle concentration and deposition in the cabin environment. The particle deposited depended on particle size and inertial forces. For the breathing case, the deposition rate on the cabin surfaces was 35% for the small (0.7 μm) particles, 55% for the medium (10 μm) particle and 100% for the large (100 μm) particles. In the coughing case, the particle deposition was enhanced due to the high initial velocity. The particle deposition rate was 48%, 69%, and 100% for the small, medium and large particles, respectively.
