旋流式气液分离器内流场的数值模拟

气液分离器作为制冷系统中的关键部件,其分离性能的优劣对系统有着重要的影响。为了研究旋流式气液分离器的分离性能,首先从理论上介绍了旋流式气液分离器的分离机理,列出其主要结构参数,然后基于计算流体动力学(CFD)方法,采用Gambit建模,利用Fluent软件,对旋流式气液分离器进行了模拟仿真,并对进口附近壁面速度场、不同尺寸和进出口截面流场矢量图、纵向剖面气液体积分数分布图等进行了重点分析。仿真结果表明设计是正确、合理的。

Numerical simulation of the two-phase flow in cyclone gas-liquid separator

The separation capability of cyclone gas-liquid separator,as the main component,has the important effect on system.In order to study its separation capability,the separation theory of gas-liquid cyclone separator,including its main structure parameters,was introduced in the paper,the numerical simulation of the gas-liquid two phase flow in the separator simulations was finished based on the method of CFD in the Fluent working condition.The speed field around import section and different size,I/O section spe...
