摘　　要：通过数值模拟，分析了溢流管插入深度对油水在柱形旋流分离器中分离性能的影响。计算时，油水两相流动采用FLUENT中的混合模型，相间的相对运动采用代数滑移模型，湍流影响则使用修正的RNGK-ε湍流模型进行模拟。通过计算，获得了内溢流管不同插入深度时柱形旋流器分离器油相体积分布、压力分布、油水分离效率等结果。这些结果为进一步优化柱形旋流器结构，推进柱形旋流器在石油工业中的应用提供一定的指导。In this paper, the influence of different insertion depth of overflow tube in cylindrical cyclones on their separation characteristics is analyzed using numerical simulation. During the simulation in Fluent, the algebraic slip model which used to simulate the relative motion between water （continuous phase） and oil （particle phase）, mixture model in Fluent and the RNG K-e turbulent model are adopted. Through these the influence of different insertion depth on the oil volume fraction distribution, pressure field distribution, split efficiency and so on are got. The results can be used to optimize the structure of cylindrical cyclones and provide some guidance for their use in offshore petroleum exploitation.
