The three dimensional flow field in the triple-screw extruder with triangle configuration is the research objects of this task, including velocity field, pressure field and shear rate field etc., simulate the representative flow field in metering section of the triple-screw extruder, consisted of three-thread element with75mm pitch, has been simulated at the screw speed of 60, 120, 180, 240 and 300rpm and the flowing regulations in flow field and especially the role of the unique center zone affecting to the conveying and pressure generating ability have also been analyzed.

本课题以三角形排列的三螺杆挤出机三维流场为研究目标，研究内容包括速度场、压力场、剪切速率场等。模拟分析首先以螺距75mm的三头螺纹元件为代表，计算由其构成的三螺杆挤出机在60、120、180、240及300rpm转速下的流场，分析流动规律，并分析了特有的中心区在输送、建压方面的作用。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
