U.S.-France Cooperative Research: Advancing Liquid Sodium Experiment

这个为期三年的奖项旨在表彰美法在地球科学方面的合作，获奖者包括马里兰大学、里昂高等学院和法国原子能委员会的研究员和研究生。丹尼尔·P·莱斯罗普和让-弗朗索瓦·平顿将分别在美国和法国领导液态金属流动中产生磁场的实验。这项研究对于理解与湍流传导流体相关的非线性动力学具有重要意义。这种情况被认为发生在地球、行星体和恒星中。这些实验利用了由法国研究部建造和资助的一个新的试验性钠设施。这个设施比马里兰大学的类似实验设施容量更大。这两家美国和法国集团在流体湍流、非线性动力学和流体实验方面有着互补的技能。该奖项强调学生的互访，以促进他们的研究培训，并鼓励未来的国际合作伙伴关系。该奖项代表了美方向NSF和法国国家科学研究中心(CNRS)提出的联合建议。NSF将支付这名美国调查员和研究生的旅费和生活费。CNRS将支持法国研究人员和研究生访问美国。这项合作将促进对地球磁场以及其他行星和天体磁场的基本理解。

0129167LathropThis three-year award for U.S.-France collaboration in earth sciences involves researchers and graduate students at the University of Maryland and Ecole Normale Superieure de Lyon and the French Atomic Energy Commission in Saclay. Daniel P. Lathrop and Jean-Francois Pinton will lead in the US and France respectively in experiments in magnetic field generation in liquid metals flow. This research is relevant to understanding nonlinear dynamics associated with turbulent flow conducting fluids. Such conditions are thought to occur in the Earth, planetary bodies, and stars. The experiments take advantage of access to a new experimental sodium facility constructed and funded by the French Ministry of Research. This facility has a larger capacity than similar experimental facilities at the University of Maryland. The US and French groups have complementary skills in fluid turbulence, nonlinear dynamics, and in fluid experiments. Reciprocal visits of students are emphasized to advance their research training and encourage future international partnerships.This award represents the US side of joint proposals to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the US investigator and graduate students. CNRS will support the visits of the French researchers and graduate students to the United States. The collaboration will advance fundamental understanding of the Earth's magnetic field and the magnetic fields of other planetary and astrophysical bodies.
