为了考察水下分离器入口预分离构件在高气液比工况下的分离效果,利用流体动力学软件FLUENT对其进行数值模拟。针对水下分离器3种长径比和3种入口倾角,建立了9个入口预分离构件的物理模型,通过模拟计算得到了各模型内部速度分布云图、速度曲线图及液滴分离效率图,并进行对比分析。结果表明:不同长径比和入口倾角对入口预分离构件内部流场的影响程度不同,长径比为4∶1、入口倾角为0°的入口构件内部流场最稳定,气液分离效果最好。
In order to investigate the separation effect of pre-separation components at inlet of submerged separator under high gas-liquid ratio conditions, the numerical simulation was carried out by using the fluid dynamics software FLUENT. According to the three aspect ratios and the three entrance inclinations of underwater separator, the physical model of nine pre-separated components was established. The velocity profile, velocity profile and droplet separation efficiency map of each model were obtained by simulation. And comparative analysis. The results show that the influence of different aspect ratios and inlet angles on the flow field inside the inlet pre-separation element is different. The aspect ratio is 4:1 and the inlet flow angle is 0 °. The internal flow field is the most stable and the gas-liquid separation effect is the most it is good.
