Intellectual Merits: The interaction of a flowing fluid and a deformable structure or solid is one of the richest sources of mathematical challenges and fundamental physical phenomena with important applications to engineering and technology including energy harvesting and power generation. The physical phenomena of interest range from blood flows in arteries, to airflow over an oscillating tongue that can lead to clinical dangerous and potentially fatal oscillations, to flow over flexible long span bridges and tall buildings, to flow over and around flight vehicles over a wide range of scales from micro air vehicles to modern passenger airliners, to fluid-structural systems whose limit cycles may be a source of energy harvesting and power generation. It is this last application that motivates much of the proposed work. While in many applications the concern is that the limit cycle oscillations will damage the mechanical integrity of the fluid/structural system, in the energy harvesting and power generation application these oscillations will be both novel and beneficial.The methods that have been proposed to better understand and exploit these phenomena include theoretical models of high sophistication including the continuum models of the fluid and the structure. While analytical solutions continue to be sought and found, computational models that tax the resources of the most powerful computers also play an important role, as do scale model experiments based upon a sound fundamental analysis and understanding of the first principles of the relevant continuum models. Indeed, it is by exploiting the complementary strengths of each approach theoretical modeling, computational modeling, and experimental scale models that the deepest and richest insights can be obtained.Broader Impact: This proposal brings together senior investigators from three major research institutions covering a wide range of intellectual experience from modern mathematics to rigorously based computational models to multidisciplinary experiments to address fluid-structure interaction phenomena. This research will also provide an opportunity for graduate students and post-doctoral visitors to participate and learn in this rich environment.

智力优势：流动流体和可变形结构或固体的相互作用是数学挑战和基本物理现象的最丰富来源之一，在工程和技术中具有重要应用，包括能量收集和发电。感兴趣的物理现象的范围从动脉中的血液流动，到可能导致临床危险和潜在致命振荡的振荡舌头上的气流，到柔性大跨度桥梁和高层建筑物上的流动，到从微型航空器到现代客机的各种规模的飞行器上和周围的流动，其极限环可以是能量收集和发电的来源的流体结构系统。正是这最后的应用激发了许多拟议的工作。虽然在许多应用中的问题是，极限环振荡会破坏流体/结构系统的机械完整性，在能量收集和发电应用这些振荡将是既新颖又有益的方法，已经提出了更好地理解和利用这些现象包括理论模型的高度复杂性，包括流体和结构的连续模型。虽然分析的解决方案继续寻求和发现，计算模型的税收最强大的计算机的资源也发挥了重要作用，因为做规模的模型实验的基础上健全的基本分析和相关的连续模型的第一原则的理解。事实上，通过利用每种方法理论建模、计算建模和实验规模模型的互补优势，可以获得最深刻、最丰富的见解。更广泛的影响：该提案汇集了来自三大研究机构的高级研究人员，涵盖了从现代数学到严格的计算模型到多学科实验的广泛知识经验，以解决流体问题。结构相互作用现象这项研究也将为研究生和博士后访问者提供一个参与和学习的机会。
