摘要
用DPM模型对油气分离器内的气液两相流流场进行了数值模拟。对计算结果分析发现,除了离心力作用可以增强分离效果外,气流在壁面上的碰撞过程对提高分离效果也具有重要作用。据此提出的改型设计方案在工程试验中获得了更高的分离效率,证明本文数值模拟所用的计算模型能够满足此类计算的要求,计算后的机理分析也反映了流动的本质。
The flow field inside an oil-gas separator are simulated with Discret Phase Model（DPM）. Based on the analysis of the numerical results, find that, besides the centrifugal force, the collision of the oil so imp have b duced droplets on the wall and the velocity distribution at the exit plane of the primary separator are alortant factors to the ean made to the stru oil-gas separation efficiency cture of the separator. With According to the above analysis, modifications the modified design, the oil carry-over rate is refrom 7ppm down to 3ppm in succeeding engineering tests, and it proves that our numerical model is valid in this type of computations, and the analysis of the flow mechanism is also correct.
