Ventilation and Indoor Air Quality (IAQ) are issues of very high interest, determining comfortable conditions for occupants and no-contaminated local atmosphere. The aircraft cabins are more confined and have a higher occupant density than other indoor environments such as offices or residential houses. The passengers and the crew share a closed and ventilated cabin, which brings potential risk of infection and inhalation of airborne pollutants. The present study deals with a numerical investigation on bio-effluents transport and diffusion in ventilated aircraft cabins. Several layouts for ventilation system (Mixing Air Distribution, Under Floor Displacement, Personalized Air Distribution) are analyzed in order to strike a balance between air quality degradation and comfort conditions for passengers. Analyses are based on bio-effluent concentrations monitoring inside the cabin.
