Application of Stochastic Theories and 3D-PTV Experiments to Study Anomalous Dispersion

本项目计划在具有内嵌非均质性的多孔介质中开展三维颗粒跟踪测速实验，将以往研究均质多孔介质中的速度场和分散性的工作扩展到具有不同大小和形状颗粒的简单非均质系统。一名博士后正在意大利的一个世界级设施中进行观察两粒子相关性的实验。PI正在制定一项策略，以发展适用于异质介质的（非局部）色散理论。这笔资金是为了加强和维持该设施的工作，否则该设施将很快关闭。

0073262CushmanThe plan is to conduct 3D particle tracking velocimetry experiments in porous media with imbedded heterogeneities by using a world-class apparatus to extend previous work to study velocity fields and dispersion in homogeneous porous media to simple heterogeneous systems with varied sizes and shapes of particles. The exeriments to observe two-particle correlations are being conducted at a world-class facility in Italy by a post-doc. The PI is working out a strategy to develop (non-local) dispersion theories applicable to heterogeneous media. This funding is to augment and sustain work at a facility that would otherwise be closed down soon.
