U.S.-France Cooperative Research: Suspension Dynamics

这个为期三年的奖项将支持美国-法国在化学工程方面的合作研究，由加州理工学院的John F. Brady和尼斯大学的Georges Bossis共同完成。他们的研究目标是证明短期范围的排斥不会改变硬球悬浮液的流变行为，并确定可以在不熔化化学链的情况下用于电流变流体的最小颗粒尺寸。这项研究涉及到斯托克动力学的使用。他们将致力于第三个，但相关的项目，一个关于悬浮动力学的专著。美国和法国的研究人员长期合作，是斯托克动力学的共同发明者。美国研究人员和他的小组将进行电流变流体模拟。这将由法国调查人员对短期排斥的模拟工作加以补充。该项目将促进我们对悬架物理及其在新材料工程中的作用的理解。

This three-year award will support U.S.-France cooperative research in chemical engineering between John F. Brady of the California Institute of Technology and Georges Bossis of the University of Nice. The objectives of their research are to demonstrate that short-term range repulsion does not change the rheological behavior of hard-sphere suspensions, and to determine the minimum size of a particle which can be used in electrorheological fluids without melting the chemical chains. The research involves the use of Stokesian dynamics. The will work on a third, but related project, a monograph on suspension of dynamics. The U.S. and French investigators have a long-standing collaboration and are co-inventors of Stokesian dynamics. The U.S. investigator and his group will carry out the electrorheological fluid simulations. This will be complemented by French investigators work on the simulations of short-term range repulsions. The project will advance our understanding of the physics of suspensions and their role in the engineering of new materials.
