| 摘 要： | 取背景风速为零的房间,动态模拟分析了人体活动对室内气流分布的影响。结果表明,人体活动会对室内气流压力、速度及污染物分布产生一定程度的影响,对温度分布的影响可以忽略。认为对医院关键科室污染物控制的研究应考虑人或物移动的影响,对此类问题的CFD模拟应采用动态方法进行,为降低污染物传播应尽量减少人或物不必要的移动。

| Abstract: | Dynamically simulates and analyses the impact of man's walking in stagnant air on indoor air distribution. The results show that man's movement affects air pressure, air velocity and contaminant distribution, while the impact on air temperature can be ignored. Based on the simulation, concludes that the impact of man's or equipment's movement should be taken into account and reduced in air pollution control in crucial medical rooms, and a dynamic CFD simulation method is preferred in this condition. |
