| 中文摘要: |
| 设计新型微肋转子的三维物理模型，利用ProE/Polyflow软件对微肋转子混炼流场进行有限元模拟和分析。结果表明，两对微肋结构增大了胶料的压力梯度、速度梯度、粘度梯度和混合指数（在0.5～0.6区间内），胶料受到的剪切作用增强，且产生一定的拉伸作用，有助于胶料的混合和分散。 |
| 英文摘要: |
| The three dimensional physical model of a novel micro fin rotor for mixer was designed，and the finite element simulation and analysis on the mixing flow field of the micro fin rotor was carried out by using ProE/Polyflow software.The results showed that，the micro rib structure increased the pressure gradient，velocity gradient and viscosity gradient，and hybrid index in 0.5～0.6 of the compound.The shear-ing action on the compound was enhanced，and a certain tensile action arised，which was helpful to the mixing and dispersing of the compound. |
