摘　　要：采用计算流体力学软件FLUENT 6.3对水力旋流器内的流体流场、流动结构和颗粒运动过程进行了数值模拟研究,分析了三维速度分布、压力分布、流体流动结构以及颗粒运动轨迹等内部流场特性。模拟结果表明：内旋流压力较低,外旋流压力较高,其中在轴心空气柱区域压力最低,进口部位与管壁的压力几乎处在同一等值线上;对速度场模拟后发现,旋流器内部流动为双层流动,以零轴速包络面为界,内部向上流动,外部向下流动,且流动旋向相同。模拟结果可为今后三相分离水力旋流器的设计、制造提供参考。Software FLUENT 6.3 is utilized to systemically simulate flow field,flow structure and movement of particles inside hydrocyclones,to study velocity distribution,pressure distribution,flow structure,air core,and movement tracks of particles.The results show that the pressure outside the eddy is high,in the eddy is low;the pressure in the axle center columnar air region is lowest,and regarding import spot and pipe wall,the pressure occupies about the identical isoline;the cyclone internal flowing is the double-decked flowing,internal upflow,outside down-flow,but the flow rotation is the same.The results can provide guidance for engineering design of hydrocyclone.
