Entrapment and Dissolution of Nonaqueous Phase Liquids in Heterogenous Media

9308131 Power这是一个支持研究的奖项，其目的是对非均质地下系统中的非水相液体捕获和溶解过程有一个基本的了解，并开发一个现象学模型来数学描述这些过程。研究人员计划使用一种同时涉及对问题进行实验和数学建模的方法。实验活动包括使用聚合苯乙烯模拟非水流体，这将允许可视化和表征所研究介质中的流体分布。导致这一奖项的提案是根据NSF 92-122《研究启动奖计划公告和指南》提交的。这些结果有望提供对与非水流体在多孔介质中运动有关的现象的更基本的理解，从而改进用于修复过程和系统的工程设计中所使用的模型，以净化被这些类型的流体污染的土壤。

9308131 Powers This is an award to support research, the objective of which is to develop a fundamental understanding of nonaqueous phase liquid entrapment and dissolution processes in heterogeneous subsurface systems and to develop a phenomenological model to mathematically described these processes. The investigator plans on using an approach that involves both experimental and mathematical modeling of the problem. The experimental activity includes simulation of the nonaqueous fluids using polymerized styrene which will allow visualization and characterization of the fluid distribution within the medium studied. The proposal leading to this award was submitted in response to NSF 92-122, Research Initiation Awards Program Announcement and Guidelines. Results are expected to provide a more fundamental understanding of phenomena associated with movement of nonaqueous fluids through porous media than now exists leading to an improvement in models used in engineering design of remediation processes and systems for decontamination of soils contaminated with these types of fluids.
