摘要:
液液旋流分离器内部流场复杂,现有实验条件难以得到较为清晰的流场分布和液液两相分离过程,用马丁·休教授发明的F型液液旋流分离器为研究模型,以取油水作为分离介质,采用计算流体动力学技术对液液旋流分离器进行数值模拟分析.结果表明:液液旋流分离器内部流场分布特征明显,并在圆柱段、大锥段、小锥段存在不同程度的循环流;其各截面切向速度和轴向速度分布规律与理论分析相一致,切向速度分布中在圆柱段、大锥段和小锥段上端组合涡特征明显,圆柱段和大锥段的轴向速度呈现双W形式;采用分散相模型追踪油滴运动轨迹,证明油水分离的关键在于油滴是否能够在分离区域进入内旋流.
Abstract:
To solve the problems of the complex flow field in liquidliquid hydrocyclone and the process of liquidliquid separation not acquired under the existing experimental condition,numerical simulation was performed using the F style liquidliquid hydrocyclone of Martin Thew with the water and oil as medium .The results show that the distribution characteristics of flow field are clear,the different cyclic flows existing in cylindrical section ,big cone section and small cone section.The tangential velocity and the axial velocity of each section are obvious and consistent with theoretical analysis; the combination vortex characteristics of tangential velocity in cylindrical section and big cone section and small cone section are obvious,and the axial velocity of cylindrical section and big cone section presents double W form.Tracing the trails of oil droplets by dispersed phase model indicates that whether the oil droplets enter into the inner vortex at separation region decides the separation of oilwater.
