基于CFD模拟的办公建筑呼吸道传染风险对比分析

COMPARATIVE ANALYSIS OF RESPIRATORY INFECTION RISK IN OFFICE BUILDINGS BASED ON CFD SIMULATION

目前,工程上一般采用污染物浓度模拟或者测试的方法,来对空间进行通风评价,但污染物浓度分析并不能直接评估室内的感染风险,本研究试图通过CFD模拟结合Wells–Riley模型的方法,评估在典型办公场所条件下,不同空间不同气流组织的感染风险,为办公楼的防控工程设计、设施运维提供一种定量化的分析手段。

At present,engineering generally uses pollutant concentration simulation or testing to evaluate the space for ventilation,however,pollutant concentration analysis cannot directly assess the infection risk in the room.This paper attempts to evaluate the infection risk of different airflow organization in different spaces under typical office premises conditions by CFD simulation combined with Wells-Riley model,and provide the epidemic prevention and operation and maintenance for office buildings This paper attempts to assess the infection risk of different airflow organizations in different spaces under typical office conditions through CFD simulation combined with Wells-Riley modeling,and provide technical support for the prevention and maintenance of office buildings.
