This study reviews the generation and diffusion characteristics of indoor viral aerosol particles, numerical simulation methods for the diffusion process of viral aerosols, and related research on the impact mechanism of different ventilation methods on the diffusion process of viral aerosols. Research has shown that the selection of initial conditions such as exhalation mode, initial airflow velocity, particle size, turbulence model, and calculation method for the generation of aerosol particles by the human body is of great significance for the numerical simulation of the diffusion process of viral aerosol particles. At the same time, on the basis of selecting appropriate ventilation methods, the reasonable setting of ventilation parameters (temperature, speed, height, etc.) can effectively suppress the spread of viral aerosols. This study can provide a theoretical basis for the study of related respiratory diseases, as well as technical and theoretical support for the selection of indoor ventilation methods to reduce the risk of human exposure caused by viral aerosols in the construction field. It also provides guidance and reference for aerosol transport and environmental protection in indoor atmospheric environments.
本研究回顾了室内病毒气溶胶颗粒的产生和扩散特性、病毒气溶胶扩散过程的数值模拟方法，以及不同通风方式对病毒气溶胶扩散过程影响机制的相关研究。研究表明，人体产生气溶胶颗粒的初始条件（呼气模式、初始气流速度、粒径、湍流模型和计算方法）的选择对于病毒气溶胶扩散过程的数值模拟具有重要意义。同时，在选择合适的通风方式的基础上，合理设置通风参数（温度、速度、高度等）可以有效抑制病毒气溶胶的传播。本研究可为相关呼吸道疾病的研究提供理论依据，也为建筑领域室内通风方式的选择提供技术和理论支持，以降低人类暴露于病毒气溶胶的风险。同时，本研究还为室内大气环境中的气溶胶输运和环境保护提供了指导和参考。
