"A Theoretical Study of Polymer Melt Processing Instabilities in Parallel Shear Flows Through Extrusion Dies": Research Initiation Award

本文将研究聚合物在熔融挤压模具中流动时发生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用于分析这些现象。建模将是数值的，使用基于有限元和光谱方法的技术。了解这种现象是关键的，以最大限度地提高工业生产的聚合物挤出率。

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.
