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.
