Archimedes screw generators (ASGs) are an emerging microhydro electricity generation technology. ASGs are**efficient, cost competitive and have low environmental impact. Supportive policy, public support for**environmentally sustainable power generation, and the availability of many potential installation sites all**support continued growth of the North American market for ASGs. This project builds on six years of research**collaboration between the PI and Bluestreak on ASGs, supported by NSERC Engage and CRD programs,**including a current CRD project that ends in Dec. 2018. This work has produced two generations of operational**models that predict Archimedes screw performance which have been incorporated into Bluestreak's operational**design tools, however, there is still potential and need to improve the accuracy of the ASG models. This new**project will improve the accuracy of practical ASG design tools, reducing uncertainty by increasing our**detailed knowledge of loss mechanisms in an ASG. This research will also determine methods to accurately**scale measurements from laboratory scale ASGs to full-size grid connected units, which has emerged as a key**issue. In practice, it is common to need to design installations with multiple ASGs at a single site. New models**will be extended to include systems of multiple screws, including the reservoir, dam, supply channels and**receiving basin. This research will continue to utilize laboratory and theoretical studies, and will make**extensive use of computational fluid dynamics (CFD) to investigate phenomena that cannot be directly**measured. Detailed field studies of four to six full scale ASGs are an integral part of this project. There is no**information currently available from full-scale ASGs that can be practically used for detailed validation of**models and CFD. This research will provide the basis for an accurate site-specific design process that can**provide site-optimized ASG systems. Improved understanding of ASG technology, potentially positioning**Bluestreak and Canada as global leaders in ASG technology while helping provide needed HQP with deep**expertise in sustainable energy technologies.

阿基米德螺旋发电机是一种新兴的微水电发电技术。ASG效率高，成本竞争力强，对环境影响小。支持性政策、公众对 ** 环境可持续发电的支持，以及许多潜在安装地点的可用性，都 ** 支持北美ASG市场的持续增长。该项目建立在PI和Bluestreak在ASG上的六年研究 ** 合作的基础上，由NSERC Engage和CRD计划支持，** 包括2018年12月结束的当前CRD项目。这项工作已经产生了两代预测阿基米德螺杆性能的操作 ** 模型，这些模型已被纳入Bluestreak的操作 ** 设计工具中，但是，仍然有潜力和需要提高ASG模型的准确性。这个新的 ** 项目将提高实际ASG设计工具的准确性，通过增加我们对ASG中损失机制的详细了解来减少不确定性。这项研究还将确定从实验室规模的ASG到全尺寸并网机组的精确测量方法，这已成为一个关键问题。在实践中，通常需要在单个站点设计具有多个ASG的安装。新型号 ** 将扩展到包括多个螺丝的系统，包括水库、水坝、供水渠道和 ** 接收盆地。这项研究将继续利用实验室和理论研究，并将广泛使用计算流体动力学（CFD）来研究无法直接测量的现象。对四到六个全面的ASG进行详细的实地研究是该项目的一个组成部分。目前，全尺寸ASG没有可用于详细验证 ** 模型和CFD的 ** 信息。这项研究将提供一个准确的网站特定的设计过程，可以 ** 提供现场优化的ASG系统的基础。提高对ASG技术的理解，可能使 **Bluestreak和加拿大成为ASG技术的全球领导者，同时帮助提供所需的HQP，使其在可持续能源技术方面具有深厚的 ** 专业知识。
