Twin Cities WRS Seminar
Simulation-Based Study of Geophysical and Environmental Fluid Mechanics at St. Anthony Falls Laboratory
Dr. Shen will give an overview of the water-oriented research at the St. Anthony Falls Laboratory. He will focus on the computer simulation focused study in his research group. Turbulence in upper oceans and lakes is often affected by water waves. Previous simulation-based studies often use simplified models and parameterizations for the wave effects on turbulence. With the advancements in numerical algorithms and the increase in computing power, it has recently become feasible to resolve the wave motions explicitly in the simulations of many problems. In this talk, some of our recent developments in numerical methods for nonlinear wave field evolution and turbulence in wave environment will be introduced, and then the flow physics learned from our wave-phase-resolved simulations of Langmuir turbulence will be discussed as an example of our study.
Dr. Lian Shen earned his bachelor’s degree from Department of Modern Mechanics at University of Science and Technology of China in 1993 and his doctoral degree in Fluid Mechanics at Massachusetts Institute of Technology in 2001. He is currently a Professor in the Department of Mechanical Engineering at the University of Minnesota and serves as the Director of the Saint Anthony Falls Laboratory. Dr. Shen’s research interests include computational fluid dynamics, water waves, turbulence in ocean and lake environments, and offshore renewable energy.
