          Yin Lu (Julie) Young Associate Professor Naval Architecture and Marine Engineering University of Michigan Ann Arbor, Mich. Host Armand Makowski Abstract Global climate change and depletion of fossil fuels both suggest an urgent need for clean, renewable energy. Currently, wind energy is more cost-effective than ocean energy due to active research and development over the last fifty years, but we are only beginning to explore ocean energy resources. This presentation will begin by introducing the various forms of ocean energy conversion systems with emphasis on marine turbines, which could be used to extract energy from tides, river currents, and ocean currents. The physics governing wind and marine turbines are similar. They both extract energy from the surrounding flow, and they both can be analyzed under incompressible flow assumptions. In addition, both hydrodynamic and structural dynamics need to be carefully considered in the design and analysis of wind and marine turbines. In this seminar, we will present a fully coupled, 3-D, transient fluid-structure interaction simulation method for analysis and design of large-scale marine turbines with consideration for spatially varying flow, fluid cavitation, structural stresses and deformations. Although the focus is on marine turbines, the method is also applicable for wind turbines. We will also discuss current state-of-the-art concepts, including the use of bend-twist coupling to enhance energy capture, delay cavitation inception, and extend the fatigue life of marine turbines. Finally, we will discuss current design challenges, including scaling issues, hydroelastic instabilities, power control issues, and system reliability. Biography Dr. Young is an Associate Professor at the Department of Naval Architecture and Marine Engineering at the University of Michigan. Prior to joining Michigan, she was an Assistant Professor at the Department of Civil and Environmental Engineering at Princeton University. Prof. Young received her Ph.D. from the University of Texas at Austin in 2002. She is the recipient of the ONR Young Investigator Award and the Princeton University Rheinstein SEAS Junior Faculty Award in 2005. She also received the UPS Visiting Professorship from Stanford University in 2008, and was appointed as a Senior ONR-ASEE Faculty Fellow at Naval Surface Warfare Center, Carderock Division in 2009. Prof. Young has written over a hundred journal and conference papers in the area of fluid-structure interactions related to marine and coastal structures. She is also currently the Society of Naval Architecture and Marine Engineering (SNAME) representative on the United States National Committee on Theoretical and Applied Mechanics (USNC/TAM).
