| 摘 要： | 本文用数值模拟的方法对再循环自净型排风柜的性能进行分析,当排风柜面风速一定时,改变排风柜出口处污染物浓度来分析经排风柜过滤后的空气携带污染物在房间里的速度场及浓度分布;并且模拟了房间内增加全面通风量及不同的换气次数对速度场及浓度分布的影响。

| 关 键 词： | 再循环自净型排风柜 全面通风 速度场 浓度分布 |

| Abstract: | A numerical simulation was built to investigate recirculatory filtration fume hood,with the constant face velocity,changing the concentration of pollutant filtrated by the fume hood exit filter to analyze the velocity field and concentration distribution in the room.In addition,general ventilation and different air changes per hour's influence on the velocity field and concentration distribution is also simulated. |

| Keywords: | recirculatory filtration fume hood general ventilation velocity field concentration distribution |
