U.S.-Argentina Cooperative Research Program: Hydrodynamic Dispersion and Surface Roughness

[304781]这项美国-阿根廷奖将支持纽约市立大学城市学院的Joel Koplik和German Drazer与阿根廷布宜诺斯艾利斯大学的Irene Ippolito博士合作进行了研究。Pis将使用数值模拟和实验来研究具有可控表面粗糙度的模型裂缝的输运特性。地质介质中裂缝的复杂几何形状，通常用分形面来描述，强烈地影响着系统的输运性质，如渗透率或流体携带的固体颗粒的水动力分散。将详细探讨裂缝表面的统计性质对系统输运性质的影响，特别关注同一裂缝不同区域之间的空间相关性所起的作用。目标是更好地了解裂缝介质中的流动行为，并开发计算和实验策略来表征和/或预测多孔地下地层的性质。这些结果与许多涉及水或油气藏中流体流动的过程有关。该项目将建立互利合作，将美国Pis的理论和计算专业知识与阿根廷合作者的实验专业知识相结合。这个机会将允许研究人员交换结果，并相应地设计/重新设计新的实验和模拟。

0304781KoplikThis U.S.-Argentina award will support Drs. Joel Koplik and German Drazer of CUNY City College in research collaboration with Dr. Irene Ippolito at the University of Buenos Aires in Argentina. The Pis will use numerical simulations and experiments to investigate the transport properties of model fractures with controlled surface roughness. The complex geometry of fractures in geological media, usually described in terms of fractal surfaces, strongly affects the transport properties of the system, such as its permeability or the hydrodynamic dispersion of solid particles carried along by the flow. The effect that the statistical properties of the fracture surface have on the transport properties of the systems will be explored in detail, with special focus on the role played by the spatial correlations between different regions of the same fracture. The objective is to obtain a better understanding of the flow behavior in fractured media, and the development of computational and experimental strategies to characterize, and/or predict, the properties of porous underground formations. The results are relevant to many processes that involve the flow of fluids in water or hydrocarbon reservoirs.This project will forge a collaboration of mutual benefit, combining the theoretical and computational expertise of the U.S. Pis with the experimental expertise of the Argentine collaborator. This opportunity will allow the researchers to exchange results and accordingly design/re-design new experiments and simulations.
