摘要 给出了光滑通风管道内颗粒沉降速度、沉降量和穿透率的计算方法,对光滑风道内颗粒的沉降规律、风道的过滤作用、风道所需的清洗周期进行了模拟分析。 Presents the calculation methods of particle deposition velocity, deposition quantity and penetration rate in smooth ventilation ducts. Discusses the pattern of particle deposition onto different orientation surfaces, the effect of ventilation duct as a particle filter and the accumulation time in duct.
