摘　　要：采用计算流体动力学(CFD)软件中的雷诺应力模型(RSM)对油水分离旋流器内部流场进行了数值模拟,研究发现采出液在进口处的相互流动干扰对油水分离效果有重要影响,据此提出了一种新型结构——带有空间阿基米德螺旋线进口流道和导流螺旋的油水旋流分离器。进一步的优化设计和性能试验表明:空间阿基米德螺旋线进口流道和导流螺旋实现了平滑过渡,从而得到较稳定的流场和较高的分离效率。Based on the Reynolds stress model CFD numerical simulation method, the experimental study is conducted on the oil - water two - phase flow field in oil - water cyclone separators. Research shows that the produced liquid at the entrance interferes with each other, which exerts great effect on oil -water separation. According to this, a new structure -the oil -water cyclone separator with the spatial Archimedes spiral cord imported flow channel and conduction current spiral - is proposed. Further optimal design and performance test show that smooth transition between Archimedes spiral and cyclone chamber is realized, and therefore more stable flow field and higher separating efficiency are fulfilled.
