摘要/Abstract

摘要： 为研究呼吸道病原体通过患病乘客的呼吸在飞机客舱内的传播规律,降低疾病的感染风险,构建了呼吸道病原体在Boeing737经济舱内传播的数值模型,模拟了患病乘客通过呼吸释放呼吸道病原体后,呼吸道病原体的动态传播过程以及客舱中其他乘客的被感染风险。以SEI (Susceptible Exposure Index)作为评价指标,通过改变患病乘客的座位,依据仿真数据得出使其他乘客感染风险最小的座位,并分析出患病乘客位于某些座位时,其余乘客的被感染风险最大。所得结果为研究客舱呼吸道病原体传播规律与感染风险的预测提供理论依据。

Abstract: In order to study the transmission law of respiratory pathogens through the breath of the sick passengers in the aircraft cabin and reduce the risk of infection, the numerical model of respiratory pathogens spread in Boeing737 economy cabin is established. The dynamic propagation process of respiratory pathogens released by the sick passenger is simulated. The risk of infection for other passengers is obtained. Taking SEI (Susceptible Exposure Index) as an evaluation index,,the seats with the least risk of infection for other passengers are obtained based on the simulated data by changing the seats of the sick passengers. Some seats of the sick passengers with the highest risk of infection for the remaining passengers are analyzed. The results provide a theoretical basis for studying respiratory pathogen transmission and the prediction of infection risk in the aircraft cabin.

Key words: aircraft cabin, numerical simulation, respiratory pathogens, transmission law, infection risk
