摘　　要：颗粒物试验舱是进行空气污染物研究和环境监测设备评价的必备环境模拟设备,其雾化发生器的位置设计会直接影响试验舱气流分布及舱内颗粒物浓度的分布均匀性。本文针对风扇启动、颗粒雾化发生和搅拌阶段,采用CFD仿真技术,将该发生器的侧置和顶置设计方案进行对比。结果表明:顶置设计能更好地提高舱内雾化颗粒的扩散效果,改善试验舱内颗粒浓度均匀性。Particulate matter test chamber is a necessary environmental simulation equipment for air pollutant research and environmental monitoring equipment evaluation.The location design of the atomizer will directly affect the distribution of air flow and the distribution uniformity of particulate matter concentration in the test chamber.In this paper,aiming at fan starting,particle atomization and stirring stage,CFD simulation technology is used to compare the side and top design schemes of the generator.The results show that the overhead design can improve the diffusion effect of atomized particles and improve the uniformity of particle concentration in the test chamber.
