摘要(Abstract):
通过数值模拟,分析了入口结构对油水在柱形旋流器中分离性能的影响。数值模拟时,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RNG K-ε湍流模型。获得了入口形状、入口方式和入口位置对柱形旋流器油水分离性能的影响。这些结果为优化柱形旋流器结构奠定了基础。
The influence of inlet structure on oil-water separation in a cylindrical cyclone is simulated in this paper.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-ε turbulent model are adopted using numerical simulation by Fluent software.The effect of inlet shapes、inlet cross-sectional shape and the height of inlet on oil-water separation characteristics in a liquid-liquid cylindrical cyclone have been analyzed.The numerical simulation can provide a foundation for structural optimization design of cylindrical cyclones.
