柱状气液旋流器压力场和速度场模拟分析

摘要

利用计算流体动力学(CFD)方法,采用流体力学软件FLUENT,针对柱状气液旋流分离器进行了内部流场、压力场和气相浓度的分析,得到了柱状气液旋流分离器的压力降分布特性和速度分布特性.揭示了入口位置及溢流口直径对柱状气液旋流分离器分离性能的影响.经研究发现:要使柱状气液旋流分离器具有低压力损失和高分离效率的综合性能,需要将入口位置和溢流口直径控制在一定范围.%The internal flow field, pressure field and gas concentration of gas-liquid cylindrical cyclone ( GL-CC) were analyzed and simulated with FLUENT and CFD. The distribution characteristics of GLCC pressure drop and velocity show that both inlet position and overflow tube diameter can affect separation performance; and keeping inlet position and overflow tube diameter in a certain range can achieve low pressure drop and high separating efficiency.
