SBIR PHASE I: Meshless Petrov-Galerkin Geo-Environ Technology For Wide Scale Field Uses

这个小企业创新研究第一阶段项目旨在开发一种无网格的彼得罗夫-伽辽金地质环境技术，用于大规模的现场使用。 地下水供应日益受到有机、无机和放射性污染物的威胁，这些污染物因处置不当或意外释放而进入环境。 据估计，仅美国政府场所的补救费用就高达数十亿美元。 地质环境评估工具在设计和评价补救办法和地下水长期管理方面发挥着重要作用。 提出的无网格地理环境技术将开辟一个新的时代，无需网格生成，即可轻松模拟大型复杂系统。 节点密度将动态调整，以获得准确的解决方案。 基于彼得罗夫-伽辽金的模型将为污染物迁移和补救替代方案评估提供稳定可靠的技术。 2D和3D界面显示和动画将为项目团队、决策者和监管机构之间的轻松沟通提供有效手段。 环境系统技术顾问公司提出的技术适用于联邦机构、州、县、石油设施和化学工业以巨大成本实施的许多废物场地恢复计划和地下水管理项目。

This Small Business Innovative Research Phase I project seeks to develop a meshless Petrov-Galerkin geo-environ technology for wide scale field uses. Groundwater supplies are increasingly threatened by organic, inorganic, and radioactive contaminants introduced to the environment by improper disposal or accidental releases. Estimates of remediation costs at U.S. government sites alone range into the billions of dollars. Geo-environ assessment tools play an important role in design and evaluations of remediation alternatives and long-term management of groundwater. Proposed mesh free geo-environ technology will open a new era for easy simulation of large complex systems without grid generation. Node density will adjust dynamically for accurate solution. A Petrov-Galerkin based model will provide stable robust technology for contaminant transport and remediation alternative evaluations. Interfaced 2D and 3D displays and animations will provide efficient means for easy communications within project team, decision-makers, and regulators. Consultants for Environmental System Technologies' proposed technology has applicability to numerous waste site restoration programs and groundwater management projects that are implemented at an enormous cost by Federal agencies, states, counties, petroleum facilities and chemical industries.
