9815106RenardyThis three-year award in support of U.S.-France collaborative research in applied mathematics and fluid mechanics involves Yuriko Renardy and Michael Renardy of Virginia Polytechnic Institute and State University and Stephane Zaleski of Universite Pierre et Marie Curie. Their collaboration addresses the numerical resolution of the shape of the interface separating two or more immiscible liquids. Their objective is the development of software for 3D transient simulations of the interface shapes. The US investigators bring to this collaboration expertise on physical modeling, analytical and computational techniques for study of stability of interface shapes and the appearance of new arrangements from unstable ones. This is complemented by French expertise in numerical simulation and the extension of French developed codes to two-fluid flow problems. The research results have potential industrial applications in the processing of bicomponent fibers from polymers and pipelining of viscous crude oil.

9815106雷纳德这个为期三年的奖项，以支持美国-法国应用数学和流体力学的合作研究涉及弗吉尼亚理工学院和州立大学的Yuriko Renardy和Michael Renardy以及皮埃尔和玛丽居里大学的Stephane Zaleski。 他们的合作解决了分离两种或更多种不混溶液体的界面形状的数值分辨率。 他们的目标是开发用于界面形状的3D瞬态模拟的软件。 美国研究人员为这次合作带来了物理建模，分析和计算技术方面的专业知识，用于研究界面形状的稳定性以及从不稳定的界面中出现新的排列。 法国在数值模拟方面的专业知识和法国开发的代码扩展到两种流体流动问题，对此进行了补充。 研究结果在聚合物双组分纤维的加工和稠油管道输送中具有潜在的工业应用价值。
