A class of shear flow instabilities which occur in the flow of polymers through melt extrusion dies will be investigated. A physical model devised from molecular kinetic theory will be used to analyze the phenomena. The modeling will be numerical, using techniques based on finite element and spectral methods. Understanding of such phenomena is critical to the maximizing of industrial production rates of polymeric extrusions.

本文将研究聚合物在熔体挤出机头流动过程中出现的一类剪切流动不稳定性。根据分子动力学理论设计的物理模型将被用来分析这些现象。建模将是数值的，使用基于有限元和谱方法的技术。了解这些现象对于最大限度地提高聚合物挤出物的工业生产率至关重要。
