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.

库什曼计划通过使用世界级的仪器，在具有嵌入的非均质性的多孔介质中进行3D颗粒跟踪速度测量实验，将以前研究均匀多孔介质中的速度场和弥散的工作扩展到具有不同颗粒大小和形状的简单非均质系统。观察两粒子关联的实验正在意大利的一个世界级设施中进行，由一名博士后进行。PI正在制定一项战略，以发展适用于非均匀介质的(非局部)弥散理论。这笔资金将用于扩大和维持设施的工作，否则该设施将很快关闭。
