| Description | We are pleased to welcome Lian Shen, professor of mechanical engineering at the University of Minnesota and director of the St. Anthony Falls Laboratory, for an ME seminar on Tuesday, Feb. 14, 2023 at 4 pm PT. About the seminar:
The interactions between wind turbulence and water surface waves is a classic fluid mechanics problem with many important geophysical, environmental, and engineering applications. To obtain improved understanding of wave-turbulence interaction mechanisms, we developed an advanced computational tool called Wave-Ocean-Wind (WOW) and used it to perform wave-phase-resolved simulations for nonlinear wave fields and direct numerical and large eddy simulations for turbulent air flows over waves to study different aspects of the problem, including the initial generation of waves and the nonlinear wave interactions in developing wind-wave fields. To explain the dynamics of wind over opposing waves and fast following waves, we developed a viscous curvilinear model, which was also used for the analysis of gusty wind turbulence over waves. About the speaker:
Professor Lian Shen earned his Bachelor’s Degree in Mechanical Engineering from University of Science and Technology of China and Doctor of Science Degree in Fluid Mechanics from Massachusetts Institute of Technology. He currently holds the position of Kenneth T. Whitby Professor in the Department of Mechanical Engineering at University of Minnesota. He also serves as the director of the St. Anthony Falls Laboratory. Professor Shen’s research interests include computational fluid dynamics, water waves, turbulence, geophysical and environmental fluid flows, and renewable energy. |
