0233255KoplikThis three-year award for U.S.-France collaboration involves Joel Koplik of City College, City University of New York and Jean-Pierre Hulin of the University Marie and Pierre Curie in Paris, France. The investigators propose to study several interrelated problems centered on the relationship between the fractal characteristics of the geometry of rough fractures and the transport properties of fluids within them. The key geometrical feature of this work is the self-affine nature of fracture surfaces and the resulting correlations in the velocity field when fluid flows through such a fracture. The U.S. investigator brings to this collaboration theoretical and numerical expertise. This will be complemented by the experimental studies on reconstructed fractures conducted by the French group. The joint program will entail laboratory experiments on transparent rough surfaces copied from natural rock samples with theoretical and computational studies in corresponding model fractally-rough geometries. In addition, field experiments in a granite quarry will be conducted in collaboration with the French Institute for Physics of the Earth. The project will advance understanding of the motions of fluids and particles in geological formations, with application to water supply, hydrocarbon production, and waste disposal. The work is motivated by environmental concerns about groundwater contamination and safe disposal of nuclear waste in fractured rocks. This award represents the U.S. side of a joint proposal to the NSF and the French National Center for Scientific Research (CNRS). NSF will cover travel funds and living expenses for the U.S. investigator, a postdoctoral researcher and/or graduate student. The CNRS will support the visits of the French researchers to the United States.

0233255Koplikthis Austrance合作三年奖涉及城市学院的Joel Koplik，纽约市城市大学和法国巴黎的玛丽大学和Pierre Curie的Jean-Pierre Hulin。 研究人员建议研究几个相互关联的问题，这些问题以粗糙裂缝几何形状的分形特征与其中的流体运输特性之间的关系。这项工作的关键几何特征是断裂表面的自动性质以及当流体流过这种骨折时，速度场的相关性。 美国研究人员将这种合作理论和数值专业知识带入了。 法国组进行的重建裂缝的实验研究将补充这一点。 该联合计划将需要对从天然岩石样品复制的透明粗糙表面进行实验室实验，并在相应的模型分形几何形状中具有理论和计算研究。 此外，将与法国地球物理研究所合作进行花岗岩采石场中的现场实验。 该项目将在地质形成中进一步了解流体和颗粒的运动，并应用供水，碳氢化合物生产和废物处理。 这项工作是出于对地下水污染和安全处理核废料的安全处置所激发的。该奖项代表了NSF和法国国家科学研究中心（CNRS）的联合提案的美国。 NSF将为美国调查员，博士后研究员和/或研究生提供旅行资金和生活费用。 中枢神经系统将支持法国研究人员对美国的访问。
