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.

0304781Koplik 该美国-阿根廷奖项将支持 Drs.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 博士进行研究合作。 Pis 将使用数值模拟和实验来研究表面粗糙度受控的模型裂缝的输运特性。 地质介质中裂缝的复杂几何形状（通常用分形表面来描述）强烈影响系统的输运特性，例如其渗透性或流动所携带的固体颗粒的流体动力学分散性。 将详细探讨裂缝表面的统计特性对系统输运特性的影响，特别关注同一裂缝的不同区域之间的空间相关性所发挥的作用。 目的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特性。 结果与涉及水或碳氢化合物储层中流体流动的许多过程相关。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。 这个机会将使研究人员能够交换结果并相应地设计/重新设计新的实验和模拟。
