| 摘 要： | 对全顶棚送风、相对两侧墙下回风的准单向流洁净室的气流组织进行了大涡模拟，并对模拟结果进行分析，讨论了不稳定涡流三角区的大小及其与洁净室宽度、送风口高度的关系，认为用大涡模拟所得结果更加合理。

Analysis of the unstable triangle eddy in the quasi-unidirectional flow clean room |
| |
| Abstract: | Applies the technique of turbulent eddy simulation to the airflow field of the clean room with the full ceiling air supply and lateral air return at the bottom of two side walls, and analyses the numerical simulation results. Discusses the size of the unstable triangle eddy and the relationships between the size and the width of clean room and between the size and the height of air supply inlet. Considers that the simulating results of large eddy is more reasonable. |
