SBIR Phase II: Meshless Petrov-Galerkin Geo-Environ Technology For Wide Scale Field Uses

这项小型企业创新研究(SBIR)第二阶段建议开发一种用于大规模现场使用的无网格Petrov-Galerkin地质环境技术。地下水供应日益受到有机、无机和放射性污染物的威胁，这些污染物通过不当处置或意外泄漏而进入环境。据估计，仅美国政府场所的补救费用就高达数十亿美元。无网格Petrov-Galerkin中的计算力学和航空航天的进展为稳定、准确地模拟大型地下水库提供了简单的手段，而无需网格生成。拟议的无网格地下水模型-Petrov Galerkin(MGM-PG)软件包将为高级水文学家以及地下水盆地管理人员、供应商和实地水文学家设计。米高梅-PG的潜在市场包括：(I)地下水库的数量和质量管理；(Ii)受污染场地的清理；(Iii)多雨年剩余地表水的地下储存及其用于延长吃水期(ASR项目)；(Iv)通过快速渗透和提取项目(Rix项目)安全处置处理后的污水；(V)地表水和地下水的联合使用；(Vi)垃圾填埋场；以及(Vii)受污染的大型联邦设施的清理。建议的技术适用于数以千计的EPA国家优先事项清单，用于加快污染场地的清理，也适用于由联邦机构、州、县、石油设施和化学工业实施的耗资数十亿美元的地下水管理项目。在世界范围内，只开发了4-5个地理环境代码，以满足各种社会需求。米高梅-PG将是一项新的技术进步，将促进对新研究生的无网格进步而不是旧方法的培训。

This Small Business Innovative Research (SBIR) Phase II proposes 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 that are introduced to the environment by improper disposal or accidental releases. Estimates of remediation costs at U.S. government sites alone totals into the billions of dollars. Computational mechanics and aerospace advances in meshless Petrov-Galerkin provide easy means for stable accurate simulations of large groundwater reservoirs without grid generation. The proposed software package Meshless Groundwater Model-Petrov Galerkin (MGM-PG) will be designed for advanced hydrologists as well as for groundwater basin managers, purveyors, and field hydrologists. Current software advancements will be interfaced for easy conceptual model development for various applications.MGM-PG potential market includes: (i) groundwater reservoir quantity and quality management; (ii) cleanup of contaminated sites; (iii) storage of wet year surplus surface water underground and its uses for extended draught periods (ASR projects); (iv) safe disposal of treated effluents by rapid infiltration and extraction projects (RIX projects); (v) conjunctive uses of surface and subsurface water; (vi) landfill sites; and (vii) cleanup of large contaminated Federal Facilities. Proposed technology has applicability to thousands of EPA National Priority List for expedited clean up of contaminated sites and also for groundwater management projects that are implemented at a cost of billions of dollars by federal agencies, State, counties, petroleum facilities, and chemical industries. Worldwide only 4-5 geo-environ codes have been developed for wide variety of societal needs. MGM-PG will be a new technological advancement and will promote training of new graduate students in meshless advances rather than old methods.
