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.

这个为期三年的美法化学和运输系统合作奖项涉及佐治亚理工学院、佛罗里达大学、马赛大学和理工学院的研究人员和学生。美国调查人员杰弗里·F·莫里斯和杰森·E·巴特勒以及法国调查人员伊丽莎白·瓜泽利和保罗·曼内维尔将在流体传输和固体颗粒在管道(管)中悬浮的理论和实验研究方面进行合作。将研究悬浮力学观点--颗粒影响流动过程--以及惯性的作用。重点介绍了管道中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。合作融合了美国和法国研究团队的实验和理论专业知识。这两类专业技术都在美国和法国集团。杰弗里·莫里斯以他的量化理论而闻名。这与法国调查人员的实验专业知识相辅相成。这项合作提供了一些独特的法国实验设施，这些设施配备了一个用于管流悬浮的正常运行的实验回路。这种合作促进了对与颗粒传输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。这一奖项代表了美国方面对NSF和CNRS的平行提议。NSF将支付这名美国调查员和学生的旅费和生活费。CNRS将支持法国研究人员和学生访问美国。
