摘要
采用K-ε两方程紊流数学模型,对流线型散流器顶送洁净室的流场和污染物的分布进行了数值模拟。通过对计算结果的分析,认清了各种影响因素对洁净室气流组织的作用,根据流场特点对洁净室进行分类,确定了每一类的应用范围,并提出了优化设计参数。
The flow field and the contamination distribution in the cleanroom with streamlined air-supply diffusers are simulated numerically based on the K-ε two-equation turbulence model.By analysing the results,the clearer ideas of the action of various factors on the air distribution in the cleanroom are gained.The classification as well as the using range and the excellent design parameters are obtained according to the characteristics of the field.
