密炼机二维流场的流固耦合分析

采用流固耦合模型模拟四棱和二棱同步转子密炼机二维流场，并对流场的压力、速度和剪切应力进行有限元分析。分析结果表明，在同等条件下，四棱同步转子比二棱同步转子能产生更大的胶料混炼压力区，因此其对胶料的剪切效果优于二棱同步转子。;The 2D FE model on fluid-structure interaction for 2-wing and 4-wing synchronous rotors of mixer was established and applied to analyze pressure，velocity and shear stress of flow field.The results showed that 4-wing synchronous rotor could build bigger pressure field than 2-wing synchronous rotor，then 4-wing synchronous rotor had much better shearing effect
