REU Site: Geothermal and Energy Geotechnics

能源岩土工程是一门新兴学科，岩土工程和地质工程师、地质学家和其他科学家/工程师利用工程物理和土壤力学原理来推进和设计可再生能源系统，如风能基础和集热器系统、地热热泵（非饱和土壤中的深交换井和浅系统），以及生物反应器垃圾填埋场的沼气回收。这个REU网站将吸引本科研究人员在这个新兴的发展和重要的研究领域。威斯康星大学麦迪逊分校（UW-Madison）在能源岩土工程方面处于领先地位，这一点可以从我们在风能和地热能领域的国际参与、继续教育短期课程的发展、工程学院的风能新课程、最重要的是，威斯康星深井热梯度测量、风力涡轮机岩土工程设计等多方面的研究计划中得到证明。生物反应器垃圾填埋场的沼气提取和回收，以及非饱和能源应用中湿热耦合流的物理特性。本科研究项目将集中研究与高效能源系统发展相关的重要问题，如岩土工程。这些问题包括研究非饱和土壤的热水力过程，土壤的热电阻率与物理性质（如土壤水特征曲线和颗粒性质）的相关性，用于风能系统的能量传输，威斯康星州地热潜力的评估，以及液体添加和渗滤液循环对废物压实和沼气产生的影响。所有这些问题都将岩土技术的使用与能源系统的更有效发展联系起来。本科生参与者将参与拓展和发现活动，与其他学习者互动。拟议的外展和教学活动将利用跨多个社会层面和教育环境的学习，使社会参与到科学、技术、工程和数学的需求中，以创造一个知情的公众。活动的发展是为了吸引本科生研究人员参与以下项目：以7年级和8年级为目标的獾营推广，通过1年级到8年级的推广提高可持续能源意识，以及参与能源岩土技术的继续教育课程“该网站由能源部与NSF REU项目合作资助”

Energy Geotechnics is an emerging discipline in which geotechnical and geological engineers, geologists, and other scientists/engineers employ the principles of engineering physics and soil mechanics for the advancement and design of renewable energy systems, such as wind energy foundations and collector systems, geothermal heat pumps (deep exchange wells and shallow systems in unsaturated soil), and recovery of biogas in bioreactor landfills. This REU Site will engage undergraduate researchers in this nascent area of developing and important research. The University of Wisconsin-Madison (UW-Madison) is at the leading edge of energy geotechnics as evidenced by our development of internationally attended, continuing education short courses in the areas of wind and geothermal energy, new courses in wind energy within the College of Engineering and, most importantly, multi-faceted research initiatives to measure the thermal gradient in deep wells in Wisconsin, wind turbine geotechnical design, biogas extraction and recovery in bioreactor landfills, and the physics of coupled moisture and thermal flow in unsaturated energy applications.The undergraduate research projects will focus on the study of important problems related to the development of efficient energy systems as related to geotechnics. These problems include the study of the thermal-hydraulic processes in unsaturated soils, thermal resistivity of soil as correlated to physical properties (e.g., soil water characteristic curves and particle properties) for its application on energy transmission of wind energy systems, evaluation of the geothermal potential in Wisconsin, and the effects of liquid addition and leachate recirculation on waste compaction and biogas generation. All these problems relate the use of geotechnics with the more efficient development of energy systems.Undergraduate participants will be involved in outreach and discovery activities engaging other learners. The proposed outreach and teaching activities will leverage learning across multiple societal levels and education environments to engage society on the need for Science, Technology, Engineering, and Mathematics in creating an informed public. Activities are developed to engage undergraduate researchers within the following programs: Camp Badger Targeted 7th and 8th Grade Outreach, Increasing Sustainable Energy Awareness through Grade 1 to 8 Outreach, and participation in Continuing Education Courses in Energy Geotechnics"This site is co-funded by the Department of Energy in partnership with the NSF REU program"
