REU Site: Geothermal and Energy Geotechnics

能源岩土工程是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发展和设计可再生能源系统的一门新兴学科，如风能基础和集热器系统、地热热泵(非饱和土壤中的深层交换井和浅层系统)以及生物反应器垃圾填埋场中的沼气回收。这个REU网站将吸引本科生研究人员参与这一新兴领域的发展和重要研究。威斯康星大学麦迪逊分校(威斯康星大学麦迪逊分校)在能源岩土技术方面处于领先地位，这体现在我们开发了风能和地热能领域的国际参加的继续教育短期课程，工程学院内的风能新课程，以及最重要的是多方面的研究计划，以测量威斯康星州深井的热梯度，风力涡轮机岩土技术设计，生物反应堆垃圾填埋场的沼气提取和回收，以及非饱和能源应用中的湿热耦合物理。本科生研究项目将专注于与开发与岩土技术相关的高效能源系统的重要问题的研究。这些问题包括非饱和土壤中的热-水力过程的研究，土壤热电阻率与风能系统能量传输的物理性质(如土壤水特征曲线和颗粒特性)的相关性，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。所有这些问题都与使用岩土技术与更有效地开发能源系统有关。本科生参与者将参与与其他学习者接触的外展和探索活动。拟议的外展和教学活动将利用跨越多个社会层面和教育环境的学习，让社会参与到对科学、技术、工程和数学的需求中，创造一个知情的公众。开展活动是为了让本科生研究人员参与以下计划：以獾为目标的7年级和8年级外联，通过1年级到8年级的外联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计划共同资助。

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"
