abstractcts - 0132730 r。本研究的目标是：(1)为设计、优化和控制聚合物材料的制造过程开发高效、强大的三维仿真工具；(2)利用仿真工具研究工业过程中可能遇到的复杂几何形状聚合物流动的恒温效应。要考虑的问题是同心圆柱体内的流动、通道内圆柱体阵列的流动、多层剪切流动、单轴和/或双轴延伸以及纤维纺丝。拟议研究的更广泛影响是开发工业过程的仿真工具，培养研究生在材料研究和开发方面的能力，并增强本科生的设计经验。

AbstractCTS-0132730R. Sureshkumar, Washington UniversityThe objectives of this proposed research are: (1) to develop efficient and robust three-dimensional simulation tools for the design, optimization, and control of manufacturing processes of polymeric materials, and (2) to use the simulation tools to investigate thermostatic effects on the stability of polymeric flows in complex geometric shapes likely to be encounter in industrial processes. The problem to be considered are flow in concentric cylinders, flow through arrays of cylinders in a channel, multilayer shear flows, uniaxial and/or biaxial extension, and fiber spinning. The broader impact of the proposed research is the development of simulation tools for industrial processes, to train graduate students in materials research and development, and to enhance the undergraduate students' design experience.
