插閂型分配式混合元件於單螺桿押出機之最佳化設計

Abstract

對於分配式混合元件(Distributive Mixing Element)的研究，於以往的專家學者大都以提出不同的流動模型，或是混合元件的實際實驗來當作主要的研究，而提出關於混合元件模擬方面的論文並不多。 本論文主要的研究目的，便是利用有限元素法(Finite element method)來模擬高分子流體於分配式混合元件流動時，幾何形狀的改變對於混合效益之影響。藉由改變插閂（pin）的構形、橫截面安裝數量以及插閂的軸向間距做一個探討與分析，並以界面面積比（interfacial area ratio）和能量消耗量(energy consumption)做為混合標的藉此研究其混合程度。

Most scholar and experts formerly put forward the practical experi -ment of different fluid model or mixing elements as the main research , when mentioning the research of distributive mixing element but not many of them worked out their essays about mixing element in simulation. The goal of my essay is to use finite element method to simulation high molecular polymer flow in the distributive mixing elements. With changing different configuration of pins, the distances between two pin along the circumferential direction and the two row of pins along the screw axial distances make quantitative analyses. Moreover, the interfacial area ratio and energy consumption are employed to indicate the mixing effect.
