0129079MorrisThis three-year award for US-France collaboration in chemical and transport systems involves researchers and students at Georgia Institute of Technology, University of Florida, University of Marseilles, and the Ecole Polytechnique. The US investigators, Jeffrey F. Morris and Jason E. Butler, and the French investigators, Elisabeth Guazzelli and Paul Manneville, will collaborate on theoretical and experimental studies of fluid transport and suspension of solid particles in pipes (tubes). The suspension mechanical perspective - in which particles impact the flow processes - and the role of inertia will be studied. Particle fraction and velocity distributions in pipes, flow structures and stability, bulk stresses in particle-laden liquids are emphasized.The collaboration merges experimental and theoretical expertise of the US and French research teams. Both types of expertise reside in the US and French groups. Jeffrey Morris is known for his quantitative theories. This is complemented by the French investigator's experimental expertise. The collaboration provides access to some unique French experimental facilities equipped with a functioning experimental loop for pipe flow suspensions. This collaboration advances understanding of engineering problems related to particulate transport. These problems are important in numerous industrial and geotechnical areas and processes, including fluvial and oceanic sediment transport and deposition. This award represents the US side of parallel proposals to the NSF and the CNRS. NSF will cover travel funds and living expenses for the US investigator and students. The CNRS will support visits by French researchers and students to the United States.

0129079Morris 这个为期三年的美法化学和运输系统合作奖涉及佐治亚理工学院、佛罗里达大学、马赛大学和巴黎综合理工学院的研究人员和学生。 美国研究人员 Jeffrey F. Morris 和 Jason E. Butler 以及法国研究人员 Elisabeth Guazzelli 和 Paul Manneville 将合作开展管道中固体颗粒的流体输送和悬浮的理论和实验研究。 将研究悬浮机械视角（颗粒影响流动过程）和惯性的作用。 重点研究管道中的颗粒分数和速度分布、流动结构和稳定性、含颗粒液体中的体积应力。此次合作融合了美国和法国研究团队的实验和理论专业知识。 这两种类型的专业知识都集中在美国和法国集团中。 杰弗里·莫里斯以其定量理论而闻名。 法国研究人员的实验专业知识对此进行了补充。 此次合作提供了一些独特的法国实验设施的使用权，这些设施配备了用于管流悬浮的功能性实验回路。这项合作增进了对与颗粒输送相关的工程问题的理解。 这些问题在许多工业和岩土工程领域和过程中都很重要，包括河流和海洋沉积物的输送和沉积。 该奖项代表了美国方面向 NSF 和 CNRS 提出的并行提案。 NSF 将为美国调查员和学生提供旅费和生活费。 CNRS 将支持法国研究人员和学生访问美国。
