| 摘 要： | 采用CFD软件——Fluent6．2中的雷诺应力湍流模型，对具有不同几何结构的循环旋风分离器气相流场进行数值模拟，以考察循环旋风分离器的几何结构对其流场的影响。模拟结果表明，循环管可以减小不利于气、液相分离的轴向速度并降低压降，防液罩可以在不增加压力损失的情况下增强气、液相分离的主要动力——切向速度，循环旋风分离器存在一个最佳入口直径。

| Abstract: | In order to inspect the influence of geometry of recycling cyclone on its flow field, Reynolds stress model （RSM） within Fluent 6.2 was used to simulate gas-flow field in recycling cyclone with different geometry. The results show that the recycling tube might decrease the axial velocity obstructing gas-liquid separation and depress the pressure drop, the extending skirt could increase the tangential velocity which was the main power of completing gas-liquid separation without increasing pressure drop ,there is an optimal inlet diameter in recycling cyclone. |
