9509754 Ill. Inst. / Tech. ABSTRACT When polymers are heated during flow, the distortion of the molecular chains by the shearing forces in the flow cause changes in the properties of the thermal properties of the polymer. For example, the thermal conductivity in a direction normal to the wall will be different than along the wall. The proposal is to carry out combined experimental and numerical modeling investigations of coupled heat and mass transfer in the flows of polymers, taking into consideration the effect of shear flows on the properties. Applications are to prediction of thermal effects during polymer processing, with the goal of allowing better design of polymer processing equipment..

9509754 疾病研究所/ 技术。 摘要：当聚合物在流动过程中被加热时，流动中的剪切力导致分子链变形，导致聚合物热性能发生变化。例如，垂直于壁的方向上的热导率将不同于沿着壁的热导率。该提案旨在对聚合物流动中的耦合传热传质进行组合实验和数值模拟研究，同时考虑剪切流对性能的影响。应用是预测聚合物加工过程中的热效应，目的是更好地设计聚合物加工设备。
