摘　　要：为进一步提升柱形油水分离旋流器的性能,建立三维模型,借助ANSYS系列软件,对5种入口流速、4种分流比下的流场进行了数值模拟。根据模拟结果认为:低入口流速下重力沉降分离起主要作用,随入口流速增大旋流离心分离逐渐起主要作用;不同的油水分流比不会对初始涡旋的形态及能量产生影响,但会显著影响旋流器出水含油率、油水分离率以及产水率。因此,调整合适的分流比是提升油水分离旋流器性能的关键。In order to further improve the performance of the cylindrical oil-water separation hydrocyclone,its three-dimensional model was established,and the flow fields at 5 inlet velocities and 4 oil-water ratios were simulated by ANASYS software.According to the simulation results,it is held that gravity sedimentation separation plays a major role at low inlet velocity,and cyclone centrifugal separa?tion gradually plays a major role with the increase of inlet velocity.Different oil-water flow ratios have no effect on the shape and energy of initial vortex,but significantly affect the oil content of separated water,oil-water separation rate and water yield.Therefore,proper oil-water ratio is the key to improving the performance of the oil-water separation hydrocyclone.
