  报告摘要: 

  Complex turbulent flows, spanning a broad range of spatial and temporal scales, occur in various environmental and industrial flow systems. With the exponential growth of the computing power of supercomputers, the simulation-based approach is playing a more and more important role in understanding the mechanism of complex turbulent flows, developing physics-based engineering models, and eventually helping the design of real-life complex flow systems.       

  In this talk, I will present a high-fidelity computational tool (named as Virtual Flow Simulator (VFS-Wind)) for simulating complex turbulent flows at field scale and its applications to wind and hydrokinetic energy. Specifically, this talk will include the following three topics: 

  1) A brief description of VFS-Wind with focus on different turbine parameterization methods; 

  2) Turbine wake dynamics under different terrain or incoming wind conditions for different turbine designs and in wind farms; 

  3) Physics-based reduced-order models for predicting power output of arbitrary size and layout wind farms. 

  报告人简介: 

  Xiaolei Yang received his Ph.D. degree in Fluid Mechanics fromInstitute of Mechanics, Chinese Academy of Sciences in 2010. Currently he is working as a senior research scientist in the Department of Civil Engineering, and as a lecturer in the Department of Mechanical Engineering at Stony Brook University. His research interests include developing computational methods for high Reynolds number, multi-scale, multi-physics turbulent flows and investigating the mechanism of complex turbulent flows and the related transport process in environmental and industrial applications.
