Development of a Finite-Element and Finite-Difference Based Discrete Numerical Mass Transfer Model for Instruction and Research

0088912 LeBoeuf该项目的目标是开发一个用户友好的，基本的有限元和有限差分离散数值模型，以更全面地评估一些建议的传质限制过程。 该模型将被学生，教师和研究人员用来调查和更充分地了解传质限制对自然或工程环境中污染物的分布，运输，反应和转化的影响。 该项目解决了由水和颗粒组成的两相系统中的单个颗粒;未来的工作将解决气相和最终三相（气-固-液）行为。 开发的系统将通过使用Prometheus的交互式网络环境提供给有关各方，进一步使用户和主要调查人员之间能够进行迅速的双向交流。***

0088912 LeBoeuf The objective of this project is to develop a user-friendly, fundamental finite-element and finite-difference based discrete numerical model to more fully evaluate a number of proposed mass-transfer limitation processes. This model will be used by students, faculty and researchers to investigate and understand more fully the effects of mass transfer limitations on the distribution, transport, reaction and transformation of contaminants within natural or engineered environments. This project addresses a single particle in a two-phase system comprised of water and the particle; future work would address gas-phase and, eventually, three-phase (gas-solid-liquid) behavior. The system developed will be made available to interested parties via an interactive web-based environment using Prometheus, further enabling prompt, two-way communication between the user and the principal investigators. ***
