应用 Fluent 软件中可实现 k-ε模型及多相流混合模型，对重力式油水分离器内部的三维流场进行数值模拟，得到含3种整流构件的分离器内部流场流动规律，比较了含不同构件分离器的流动与分离特性。模拟结果表明，该方法可以较好地模拟出油、水两相在分离器内部的流动情况。结果显示，田字板式整流构件对流型的整流作用较显著，有效抑制了分离空间内的返混流动。改进后的上部不开孔田字板式整流构件的流动特性和分离特性均优于改进前结构。模拟结果说明，通过数值模拟方法得到的数据可为稳流构件的优化提供参考。

The realizable k-ε model and the multiphase mixture model of Fluent software are used to simulate flow field of gravitational oil-water separators.The distribution of flow field in the separator with three different flow regulating components is obtained.Flow field and separa-tion characteristics of separators with different components are analyzed and compared.The re-sults show that flow of oil-water two-phase in the separator can be simulated well with this meth-od.Square orifice plate restrains back-mixing flow in separation space effectively.Improved square orifice plate has better flow and separation characteristics than the previous one.Valuable guidance can be provided by the method of numerical simulation for steady flow component opti-mization.
