以Ｋ－ε紊流模型为基础，采用有限差分的方法，对矢流洁净室三维紊流流场和污染物的分布进行了数值模拟，并在模型洁净室内放置工作台和点污染源，对矢流洁净室做了实验研究。对实验结果和计算结果的对比和分析，揭示了矢流洁净室内气流的流动特性和污染物的分布规律，得到了这种洁净室的一些主要设计参数。 Based on the K-ε turbulence model, the finite-difference method was used to numerically simulate the three-dimensional turbulent flow field and the distribution of pollutants in the vector flow clean room, and the workbench and point pollution sources were placed in the model clean room. An experimental study was conducted on the flow clean room. The comparison and analysis of the experimental results and the calculated results revealed the flow characteristics and the distribution of pollutants in the clean air flow in the vector flow, and some of the main design parameters of the clean room were obtained.
