Interfacial Shapes in the Design of Composite Polymeric Materials

勒纳尔迪 这个化学研究热项目关注的是化学和热系统中分离两种不混溶液体的界面形状。 双流体的现象是完全出乎意料的知识，从一个流体流动，形成一个学科丰富的交叉科学。 工业应用包括形成双组分纤维如尼龙和生产照相胶片。 从理论上讲，分离两种流体的边界形状通常有多种可能性。 此外，实验表明，一些形状是优于其他的，因此，选择机制应进行研究，以减少理论预测和实验结果之间的差距的目标。 溶解的添加剂和温度梯度的影响，以及在界面处的传热和传质的考虑在许多化学过程中是重要的。 物理模型，分析和计算技术将用于研究各种界面形状的稳定性，以及从不稳定的新安排的出现。 复合材料的力学性能与界面形状密切相关。 因此，了解组件属性对界面形状的影响具有实际意义。 ***

Renardy 9307238 This chemical research thermal project concerns the shape of the interface separating two immiscible liquids in chemical and thermals systems. Two-fluid exhibit phenomena which are totally unexpected from a knowledge of one-fluid flows and form a subject rich in interdisciplinary science. Industrial applications include the formation of bicomponent fibers such as nylons and the production of photographic films. Theoretically, there are often many possibilities for the shape of the boundary separating the two fluids. In addition, experiments show that some shapes are preferred over others, so that the selection mechanisms should be investigated with the goal of lessening the gap between theoretical prediction and experimental results. The effect of dissolved additives and temperature gradients, and the consideration of heat and mass transfer at an interface are important in many chemical processes. Physical modeling, analytical and computational techniques will be used by the proposer to study the stability of various interface shapes, and the appearance of new arrangements from unstable ones. The mechanical properties of composite materials are strongly dependent on interface shapes. Thus, an understanding of the effects of the component properties on interface shape is of practical importance. ***
