CAREER: Spatial and Temporal Characterization of Dense Nonaqueous Phase Liquids in Porous Media Using Magnetic Resonance Imaging

Werth 9733428该奖项旨在支持符合教师早期职业发展（Career）计划（NSF 97-87）提案提交指南的项目。首席研究员的目标是进行研究，以帮助确定间隙水速度、孔隙和非水相液体性质对非水相液体与地下水之间有效界面区域特征的影响，并预测非水相液体在天然多孔地下水含水层中的溶解随时间的变化。他计划利用磁共振成像来可视化非水相液体与水之间界面的局部间隙速度、孔隙尺寸和其他行为特征，以阐明控制非水相液体溶解的机制。根据NSF 97-87，首席研究员计划利用交互式模拟模型和案例研究将他的研究结果整合到课堂教学中。这种方法预期将大大加快他的研究成果从课堂环境转移到考虑将其用于工程设计和执行解决有关“现实世界”危险废物管理问题的系统。* * *

Werth 9733428 This is an award to support a project proposed in accord the with Guidelines for Submission of Proposals to the Faculty Early Career Development (CAREER) Program, NSF 97-87. The Principal Investigator's objectives are to conduct research that will assist in determining the effects of interstitial water velocity, pore and nonaqueous phase liquid properties on the characteristics of the effective interfacial region between nonaqueous phase liquids and groundwater, and predict time- dependent dissolution of nonaqueous phase liquids in natural porous groundwater aquifers. He plans on using magnetic resonance imaging to visualize local interstitial velocities, pore dimensions and other behavior characteristics of the interfaces between nonaqueous phase liquids and water to elucidate the mechanisms controlling dissolution of nonaqueous phase liquids. In accord with NSF 97-87, the Principal Investigator plans on integrating the results of his research into classroom instruction using interactive simulation models and case studies. This approach is expected to significantly hasten the transfer of the results of his research from the classroom setting to consideration of its use in engineering design and implementation of systems for solving relevant "real-world" hazardous waste management problems. ***
