CNIC: U.S.-Danish Research Planning Visit to Catalyze Computational and Engineering Research on Scour Protection of Offshore Wind Farms

此次对丹麦技术大学（DTU）的研究计划访问将使德克萨斯大学圣安东尼奥分校（UTSA）的刘晓峰教授能够与丹麦同行B教授开展合作。Mutlu Sumer，关于海上风电场基础冲刷防护的新兴话题。 刘教授将在一名美国研究生的陪同下，为设想中的联合研究带来建模和计算专业知识，而由Sumer教授领导的DTU研究团队将在风力涡轮机基础的侵蚀和冲刷影响领域提供重要的专业知识。 通过一系列技术演示、小组讨论和对丹麦风能公司的实地考察，研究人员打算将他们的计划集中在对海上基础冲刷所涉及的流体动力学机制进行更广泛的检查上。 初步结果应能为受多孔石层保护的桩体周围的湍流结构提供新的见解，目标是定义新的工程解决方案，解决与海上风电场的稳定性和建设相关的问题。如果成功，该奖项将促进新的美国-丹麦研究合作。 更广泛的影响可能包括适用于今后防止损害海底海上设施的工作的新知识。 此外，美国学生的早期职业参与将为个人和丹麦机构提供有价值的专业介绍，这些机构在与无碳风能发电相关的广泛主题方面具有专业知识。

This research planning visit to the Technical University of Denmark (DTU) will enable Prof. Xiaofeng Liu from the University of Texas at San Antonio (UTSA) to initiate collaboration with Danish counterpart, Prof. B. Mutlu Sumer, on the emerging topic of foundation scour protection for offshore wind farms. Prof. Liu, accompanied by one U.S. graduate student, will bring modeling and computational expertise to the envisioned joint research while the DTU research team headed by Prof. Sumer will contribute significant expertise in the area of erosion and scour effects on wind turbine foundations. Through a series of technical presentations, group discussions, and site visits to wind energy companies based in Denmark, the researchers intend to focus their plans for a more extensive examination of fluid dynamic mechanisms that are involved in the scouring of offshore foundations. Preliminary results should provide new insight into the turbulent flow structures around piles protected by porous stone layers, with the goal of defining new engineering solutions that address issues related to the stability and construction of off-shore wind farms.If successful, this award will catalyze a new US-Danish research collaboration. Broader impacts may include new knowledge applicable to future efforts to prevent damages to offshore installations on seabed. Furthermore, the U.S. student's early career involvement will provide a valuable professional introduction to individuals and Danish institutions with expertise in a wide range of topics associated with the generation of carbon-free wind energy.
