The mixing ventilation (MV) system could spread airborne infectious diseases in airplane cabins, such as the flu and Corona-virus infection (COVID-19). As a result, it is critical to improve the current design of airline cabin ventilation systems. Six innovative customized ventilation (PV) systems were proposed and investigated through numerical simulations in this study to reduce pollutant transport. At first, two environmental chambers' experimental data on airflow, air temperature, and pollutant concentration were utilized to validate the Computational Fluid Dynamics (CFD) model used for the present numerical study. The six PVs were then studied to analyze the distributions of air velocity, air temperature, pollutant concentration, and carbon dioxide (CO 2 ) concentration in a part of the Boeing 767 cabin using the validated CFD model. It is found that the passenger's personal outlet set up on both sides of his or her head (PV-1) has the best distribution of carbon dioxide concentration, velocity, temperature, and contaminant concentration when compared to the six personalized air distribution systems. It can reduce pollutant concentrations more than the other proposed systems. The present study may shed new light on the design of PVs with the potential for reducing the spreading of airborne infectious diseases.
