摘　　要：2019年末爆发的新型冠状病毒肺炎疫情对现有医疗系统造成了巨大压力,各地开始建设新型冠状病毒肺炎的集中治疗临时医院。临时医院排风口排出的气体可能对临时医院新风口或者周围环境造成污染。由于临时医院的设计和建造周期只有6 d^10 d,因此排风环境影响分析一般需要在几小时内完成。基于上述背景,该研究提出了一个临时医院排风环境影响的快速模拟方法。该方法以开源流体力学计算软件FDS为基础,实现了临时医院建筑的快速建模、基于云计算平台的分布式计算、以及有害空气流动的监测和可视化,为临时医院设计阶段的快速分析提供了专门工具。并以武汉雷神山医院为案例,说明了该方法在此次肺炎疫情防疫工作中的应用价值。The outbreak of the novel coronavirus pneumonia at the end of 2019 imposed severe pressure on the medical system of China.Several Chinese cities began to build temporary hospitals for the centralized treatment of the pneumonia patients.Because the design and construction of the temporary hospital must be completed in 6 to 10 days,only a few hours are allowed for the analysis of the impact of exhausted air on the surrounding environment.To overcome this difficulty,a high-efficiency simulation method for analyzing the impact of exhausted air is proposed in this study.Based on the open-source computational-fluid-dynamics(CFD)software FDS,the proposed method realizes the fast modeling of temporary hospitals,the cloud computing-based CFD computation,and the monitoring and visualization of harmful air.The proposed method provides an efficient tool for the rapid analysis in the design stage of new-built temporary hospitals.A case study of Wuhan Leishenshan Hospital was conducted to demonstrate the application value of the proposed method in the epidemic prevention of the pneumonia.
