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

一类剪切流不稳定性， 将研究聚合物通过熔体挤出模头的方法。 物理 从分子动力学理论设计的模型将用于分析 现象。 建模将是数字化的，使用基于 有限元和谱方法。 了解这些 这种现象对工业生产率的最大化至关重要 聚合物挤出物。

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.
