| 摘 要： | 气流流型主要受送回风口的位置、尺寸、房间几何形状及室内设备的影响 .基于 k- ε两个方程的紊流模型对矢流洁净室在不同情况下的气流分布和浓度场进行了三维数学模拟与优化 ,并进行了模型试验 .根据理论分析和实验结果 ,得出了气流及污染控制特性、节能效果等方面结论 ,证明了送风量仅相当于 13～ 12 常规换气次数的条件下即可达到美国联邦标准 1 0 0级的洁净度 ,同时可降低层高 ,简化系统 .这些结论将有助于促进这种新流型在中国的应用

| Abstract: | Based on K-ε two equation turbulence model,the air distribution and contamination field under different conditions was numerically simulated in a vector-flow cleanroom.Special mesh system was introduced to deal with the qu arter-circle-shaped inlets.Model experiments were also made.By analysis of num erical as well as experimental results,we made some predictions about flow chara cteristics,contaminant control effect and ventilation performance of this energy -saving cleanroom.It has been proved that the vector-flow can meet class 100 o f Fed. St.with 1/3 to 1/2 conv entional air change per hour,and re-duce layer height and simplify air clean system. |
