针对矢流洁净室这种新型、节能的洁净室，本文用数值摸拟和模型实验两种方法对其进行了研究．模型实验实测了空态和静态两种工况下模型矢流洁净室室内流场和浓度场，给出了流场图和浓度场实测结果；数值模拟方法，根据ｋ─ε紊流模型，采用有限差分法，对两种工况下矢流洁净室室内流场和污染物的分布进行了计算机求解，得出室内流场图及污染物分布特性．通过对两种方法所得结果进行分析和比较，证明了矢沈洁净室净化的基本原理，得出矢流洁净空室内流场特点有利于其达到较高级别洁净度，且浓度场实测结果证明该种洁净空可以达到较高级别的洁净度。建议某些场合推广使用矢流洁净室。
For the new-type, energy-saving clean room of the vector flow clean room, this paper studied it by numerical simulation and model experiment. The model experiments measured the flow and concentration fields in the vector flow clean room under both air and static conditions, and presented the flow field and concentration field measurements. The numerical simulation method was based on the k-ε turbulence model. The finite difference method is used to solve the flow field and pollutant distribution in the vector flow clean room under two operating conditions. The flow field diagram and the pollutant distribution characteristics are obtained. Through the analysis and comparison of the results obtained by the two methods, the basic principle of the clean-up of the vector clean room is proved. It is concluded that the flow field characteristics of the clean-air clean room in the vector flow are conducive to achieving a higher level of cleanliness, and the measured results of the concentration field prove that The clean air can reach a higher level of cleanliness. It is recommended to promote the use of vector-flow clean rooms on certain occasions.
