提出了一种高保真的病原体在移动行人中通过气溶胶传播的模型。关键思想是计算流体动力学和计算群体动力学的紧密耦合，以便在空间和时间上捕捉病原体负荷的排放、运输和吸入。一个模拟病原体在有移动行人的狭窄走廊中传播的例子清楚地表明，行人的运动对气流有相当大的影响，从而对病原体的传播和潜在的传染性有很大的影响。
A high fidelity model for the propagation of pathogens via aerosols in the presence of moving pedestrians is proposed. The key idea is the tight coupling of computational fluid dynamics and computational crowd dynamics in order to capture the emission, transport and inhalation of pathogen loads in space and time. An example simulating pathogen propagation in a narrow corridor with moving pedestrians clearly shows the considerable effect that pedestrian motion has on airflow, and hence on pathogen propagation and potential infectivity.
