| 摘 要： | 使用FLUENT软件中的多相流欧拉分析方法，结合雷诺应力湍流模型，实现单锥型旋流器内油水分离过程的三维数值模拟并预测其分离效率。该模拟可用于分散相的体积率超过10％、湍流具有各向异性结构的一般广义情形。模拟展示了油水两相由开始的均相来流如何在单锥旋流器内逐渐分离、聚合、迁移的过程。本文对旋流器分离性能的预测得到了实测结果的验证。

| Abstract: | A three-dimensional oil-water 2-phase turbulent flow and separation process in a singlecone hydrocyclone is numerically simulated using FLUENT software. The Eulerian model of a multiphase flow and Reynolds-stress turbulence model are both applied to this simulation for general applications, concerning with phases with volumetric ratio over 10% and anisotropic turbulent flow dominated by swirling in the hydrocyclone. It is well shown in the simulation that how separation, aggregation and shift of oil and water proceed in a single-cone hydrocyclone. The current simulation is verified by comparing predicted and measured separation efficiency of the hydrocyclone. |
