This research paper presents an analysis of the propagation of the SARS-CoV-2, or other similar pathogens, in a hospital isolation room using computational fluid dynamics (CFD) and Lagrangian Coherent Structures (LCS). The study investigates the airflow dispersion and droplets in the room under air conditioning vent and sanitizer conditions. The CFD simulation results show that both the air conditioner and sanitizer systems significantly influence the dispersion of the virus in the room. The use of LCS enables acquiring a deep understanding of the dispersion of suspended particles, providing insights into the mechanisms of virus transmission. The findings of this study could help in developing strategies for improving the design and operation of isolation rooms to minimize the likelihood of virus dissemination within hospitals.
本研究论文运用计算流体动力学(CFD)和拉格朗日相干结构(LCS),对严重急性呼吸综合征冠状病毒2(SARS-CoV-2)或其他类似病原体在医院隔离病房中的传播进行了分析。该研究调查了在空调通风口和消毒剂条件下病房内的气流扩散和飞沫情况。CFD模拟结果表明,空调系统和消毒系统均对病毒在病房内的扩散有显著影响。使用LCS能够深入了解悬浮颗粒的扩散情况,为病毒传播机制提供见解。本研究结果有助于制定策略,改进隔离病房的设计和运行,以降低医院内病毒传播的可能性。
