| 摘 要： | 针对孔板送风的乱流洁净室，运用CFD软件对不同换气次数条件下的气流组织和污染物扩散进行数值模拟分析。通过对15～70换气次数的洁净室的数值模拟，比较了不同换气次数下洁净室的排污效率；通过模拟对比，得出在换气次数为55次时．房间的排污效率最好；并为工程设计提供了一定的理论依据。

| Abstract: | This paper analyzes and simulates the effect of the air change rate per hour (ACH) on contamination diffusion airflow field in turbulent clean-room of hole-board ventilation by using CFD. The quality of Contaminant Removal Effectiveness (CRE) is compared with ACH ranging from 15 to 70. According to the simulation,it is the best condition of CRE in clean room when air change rate is 55 per hour,and the conclusion provides a theoretic basis for engineering design. |
