摘要: 洁净室作为一种可以在生产过程中对空气中微粒数量进行限制的空间，被广泛应用于化工及制造行业。本文将双向拉伸聚酯薄膜(简写：BOPET)洁净生产车间作为研究对象，利用计算机流体动力学(CFD)技术模拟了两种常见的洁净室空气流动模式，通过对流线的分析，发现其在BOPET行业中的应用存在一些不足和局限性。因此，本文针对BOPET车间设计并测试了一种新的空气流动组织方案，该设计在实际的BOPET车间得到了成功的应用。随后通过建立一个更加复杂和贴合实际的车间仿真模型，将仿真数据与实测数据进行比较，验证了CFD模拟结果的合理性和准确性。最后采用清洁度测试仪记录颗粒浓度和洁净等级，新设计车间的洁净程度能够满足BOPET工业运行状态下洁净生产的要求。
Abstract: Clean room is widely used in chemical and manufacturing industry, in order to create a space with limited airborne particles for production. This study sets Biaxial-oriented polyethylene tereph-thalate (BOPET) film workshop environment as research object, using Computational Fluid Dy-namics (CFD) technology to simulate two common clean room air flow patterns. By analyzing the streamlines, some shortcomings and limitations are found in their application in the BOPET in-dustry. So, a novel air flow organization is presented and numerically investigated by CFD for BOPET workshop. Then the new air pattern scheme is successfully implemented in an actual BOPET workshop clean room. By building a more complex and realistic model for simulation and analysis, this study compares the simulation data with the measured data to validate the result of CFD simulation results. A cleanliness tester is used to record the particle concentrations and class number; the class number of the workshop under new design can meet the requirement of clean room in operation-state of BOPET industry.
