【摘要】利用FLUENT软件对在聚酯生产中应用的双层搅拌桨搅拌槽内疏水缔合聚丙烯酰胺AP-P4溶解过程的流场进行数值模拟分析,采用标准k-ε模型和多重参考系法(MRF).分析了AP-P4溶解过程中刚加入聚合物颗粒时在搅拌槽内的混合情况.得到了搅拌槽内流场状况和固体颗粒的体积分数分布.并对流场的分布规律、固体颗粒体积分数分布特点加以分析,由模拟结果计算出搅拌轴的功率,为搅拌槽的设计和实际应用提供有益的结论.%The FLUENT was used to simulate dissolution process' flow field of hydrophobic associating poly-acrylamide AP-P4 in the stirred tank is mixed with dual impellers, in the simulation, both turbulent model ( k-e)and multiple reference method(MRF) were used. Through analyzing mixed condition in the tank when polymer particles is put in the AP-P4 dissolution process, the flow field changes in the stirred tank and the volume fraction distribution of the solid particles were obtained; meanwhile, through analyzing the flow field' s regularities of distribution and the volume fraction characteristics of solid particles as well as the simulation, the agitator shaft' s power can be calculated to provide the reference for stirred tank design and practical application.【总页数】5页(P193-196,202)
