摘要:
利用商业计算流体力学软件Fluent 6.1对不同结构尺寸以及运行条件下旋风分离器内部气相流场进行了数值模拟,基于响应曲面法并利用统计软件Minitab V14得到了旋风分离器自然旋风长新的预测模型.对预测模型分析后表明,除了入口面积和排气芯管直径影响自然旋风长外,入口风速、旋风器高度以及排气芯管的插入深度也会不同程度地影响自然旋风长.由于自然旋风长预测模型考虑了更多的影响因素,和以前的模型比较能更好地反映旋风分离器的结构尺寸及运行条件对其性能的影响.
Abstract:
Numerical simulations of cyclone separators with various geometries and operating conditions were performed to study nature vortex lengths. The numerical solutions were carried out using commercial computational fluid dynamics(CFD)code Fluent 6.1. A new prediction model of the nature vortex length is obtained based on response surface methodology by means of the statistical software program(Minitab V14). The effects of the inlet gas velocity, the dimensions of the vortex finder and the length of the cyclone on the natural vortex length are investigated. The results indicate that the nature vortex length is also affected by the inlet gas velocity, the length of cyclone and vortex finder insertion deepness in addition to the factors proposed in the literature. Comparisons are made among the present model, published models and experimental data. The results show that the present model can estimate the effects of different geometries and operating conditions on the cyclone separator’s performance more exactly than other models.
