| 摘 要： | 使用商业CFD软件STAR-CD,建立了排气管插入深度不同的三种切向进口式旋风分离器内部流场k-ε双方程湍流模型,对切向进口式旋风分离器内部流场进行了模拟。通过分析排气管插入深度对旋风分离器流场的影响,得出了旋风分离器中的压力和速度分布,以及粒径为20μm和2μm的SiO_2尘粒运动轨迹,为旋风分离器的设计和优化提供了重要的理论依据。

| Abstract: | The k-εdouble equation turbulent flow model of three cyclone separators with different inserting depth of vent-pipe was built using commercial computational fluid dynamics (CFD) software STAR-CD,and the flow field in the cyclone separators was simulated.Through analyzing the effects on the flow field in the three cyclone separators,which is with different dimension vent-pipe.The distribution of pressure and velocity,and moving track of SiO_2 particles with dimension of 20μm and 2μm in the cyclone separators were obtained,which is an significant theoretic reference for cyclone separator design and optimization. |
