摘要
本文采用雷诺应力气流场模型(RSM)和随机轨道粒子模型,对粒子在空调系统风管渐缩段内沉降规律进行了探讨,模拟了粒径为10～200μm范围内的7组粒子,在入口平均风速分别为4 m/s、6 m/s、8m/s时,在渐缩段各个表面的沉积情况,并与渐缩段前直管段的沉积进行了对比,得出了沉积规律。
This paper discussed particle deposition in gradually reduce segment of air-conditioning duct using RSM （Reynold Stress Model） and random trajectory particle model. Simulation of particle deposition in each internal surface of gradually reduce segment with nominal particle diameters of 10-200μm were carried out with air velocity 4 m/s, 6 m/s and 8m/s. Contrasted with particle deposition of the straight duct, the deposition rule was presented.
