【摘要】 采用雷诺应力模型(RSM)和随机轨道粒子模型模拟了粒径在10~200μm范围内的9组粒径的粒子在入口平均风速分别为2、4、6、8 m/s时,在截面尺寸为160mmx120 mm的光滑水平风管内各表面的沉积,重点分析了流态对粒子在矩形空调风管内沉降的影响.结果表明,流态对粒子在通风管道内沉积的影响较小.更多还原

【Abstract】 This paper discusses particle deposition in rectangle duct using RSM(Reynold Stress Model) and random trajectory particle model,and particle deposition in each internal surface of smooth horizontal duct are simulated with nine groups of particle which nominal diameters are 10~200 μm at each of four nominal air speed:2 、4、6、and 8 m/s in the cross-section size of 160 mm×120 mm,and then emphatically analyzes the influence of flow pattern on particle deposition in rectangle duct.The results show that the flow pattern have little influence on particles deposition.更多还原
