摘要
采用计算流体力学(CFD)软件FLUENT 6.1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。
Though continuous rotor-stator mixers are widely used in many industrial processes, 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 pressure predicted by CFD was in a reasonable agreement with that given by the experiment. The maximum of shear rate, turbulent kinetic energy and the energy dissipation rate increase with the rotor speed, 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-stator mixers.
