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

0088912 LeBoeuf这个项目的目标是开发一个用户友好的、基本的有限元和基于有限差分的离散数值模型，以更全面地评估一些拟议的传质限制过程。学生、教师和研究人员将使用该模型来更全面地调查和了解传质限制对污染物在自然或工程环境中的分布、传输、反应和转化的影响。该项目解决了由水和颗粒组成的两相体系中的单个颗粒；未来的工作将解决气相，并最终解决三相(气-固-液)行为。开发的系统将通过使用普罗米修斯的交互式网络环境提供给感兴趣的各方，进一步促进用户和主要调查人员之间的迅速双向交流。***

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. ***
