飞机客舱的通风有效性是减少乘客呼出的空气传播病原体交叉污染的关键因素。在这项研究中，一个全尺寸的部分波音767飞机客舱包含35个人体模型被用来评估通风效果和表征空气分布。每个人体模型都连接有身体加热器和二氧化碳出口以模拟呼吸。通过一系列实验测量了空气的局部平均年龄和乘客呼吸水平下的通风有效因子。使用二氧化碳作为示踪气体来确定当地空气的平均年龄和VEF。使用体积粒子跟踪测速（VPTV）系统测量的空气速度分布被用来产生气流模式，并调查影响当地平均年龄的空气和VEF的基本机制。此外，在不同的送风率进行测量，以检查其对通风性能的影响。
Ventilation effectiveness in aircraft cabins is a critical factor for minimizing the cross-contamination of airborne pathogens exhaled by the passengers. In this study, a full-scale section of a Boeing 767 aircraft cabin containing thirty five mannequins was used for evaluating the ventilation effectiveness and characterizing the air distribution. Each mannequin was attached with a body heater and an outlet of carbon dioxide to simulate breathing. A set of experiment trials was conducted to measure the local mean age of air and the ventilation effectiveness factor (VEF) at the breathing level of the passengers. Carbon dioxide was used as the trace gas to determine the local mean age of air and the VEF. The air velocity profiles measured using a volumetric particle tracking velocimetry (VPTV) system was used to generate the airflow patterns and investigate the underlying mechanism affecting the local mean age of air and the VEF. In addition, measurements were conducted at different air supply rates to examine its effect on the ventilation performance.
