| 摘 要： | 采用计算流体力学（CFD）软件FLUENT6.1的标准k-ε双方程湍流模型及多重参考系（MRF）法对连续高速分散混合器内的流场进行了数值模拟，得到了不同操作转速下的压力场和速度场。所得压力模拟结果与实验数据相符，表明压力与转速成反比关系；速度场的模拟计算结果与文献值相符；同时研究了不同转速下混合器内的最大剪切速率、最大湍流动能及最大能量耗散速率随操作转速的变化规律。

| Abstract: | Though continuous rotor-stator mixers are widely used in many industrial proces ses, there are very few reports on their numerical simulation. The fluid field in a rotor stator mixer was numerically simulated by using computational fluid dynamics (CFD) package FLUENT6.1. The multi-reference frame (MRF) and the standard k-ε two equation turbulent model were used in the simulation. The velocity field predicted by CFD was in a reasonable agreement with that given by the literature. The pressu re predicted by CFD was in a reasonable agreement with that given by the experim ent. The maximum of shear rate, turbulent kinetic energy and the energy dissipation rate increase with the rotor s peed ，the minimum absolute pressure of the field decreases with the rotor speed. The results are of the importance to the optimum of industry continuous rotor-stat or mixers. |
