摘要:

针对偏心双螺杆挤出机自身结构存在的局限性,设计了一种新型偏心三螺杆挤出机。利用Polyflow软件,分析了压力场、剪切速度场、速度矢量场、混合指数、分离尺度、平均混合效率、对数拉伸率等参数;研究了偏心三螺杆挤出机的流动和混合机理,并与偏心双螺杆挤出机进行了对比分析。结果表明,在相同的条件下,偏心三螺杆挤出机拉伸折叠效果更好,混合效率高于偏心双螺杆挤出机,为进一步探究混沌混合机理和优化偏心多螺杆挤出机提供了理论依据。

Abstract:

Based on the limitation of the eccentric twin screw extruder's own structure, a new type of eccentric three screw extruder was designed. Polyflow software was used to analyze the pressure field, shree velocity field, velocity vector field, mixing index, separation scale, average mixing efficiency, logarithmic stretching and other parameters. The flow and mixing mechanism of the eccentric tri?screw extruder were studied and compared with that of the eccentric twin?screw extruder. The results show that under the same conditions, the stretching and folding effect of the eccentric three?screw extruder is better, and the mixing efficiency is higher than that of the eccentric twin?screw extruder, which provides a theoretical basis for further exploring the chaotic mixing mechanism and optimizing the eccentric multi?screw extruder.

Key words: Eccentric three?screw extruder, Eccentric twin?screw extruder, Hybrid simulation
