The large-scale outbreak of SARS-CoV-2 has prompted the restaurants and canteens to take corresponding measures such as installing diner dividers and controlling the number of diners and the distance between personals. At present airborne transmission has been deemed as one of the main spread routes of the respiratory infectious diseases. This paper adopts computational fluid dynamics to explore the impacts of dividers installation in two different dining environments on the distribution of aerosols exhaled by infectors and uses a modified Wells-Riley model to analyze the infection risk of surrounding diners. The results show that the effects of dividers on blocking the path of aerosol transmission and protecting the surrounding susceptible personals are limited to some extent. Meanwhile, the aerosols will gather in the breathing zone inside the partitioned space, and the next diner sitting in the previous infector’s seat has a certain infection risk.

SARS-CoV-2的大规模爆发促使餐厅和食堂采取了相应的措施，例如安装餐车分隔线、控制用餐人数和人与人之间的距离。目前空气传播被认为是呼吸道传染病的主要传播途径之一。本文采用计算流体动力学研究了在两种不同用餐环境中安装隔板对感染者呼出气溶胶分布的影响，并使用改进的 Wells-Riley 模型分析了周围用餐者的感染风险。结果表明，隔板对阻隔气溶胶传播路径和保护周围易感人员的作用有限。同时，
