奇米第四色在线影院摘要

  In this talk, we will provide a summary of our field research on wind turbine wake flows, atmospheric boundary layer and particle settling dynamics based on snow-powered flow visualization and super-large-scale particle imaging velocimetry (SLPIV) at the Eolos field station, Rosemount, MN, USA. Specifically, we will describe several interesting behaviors of near-wake flows (e.g., wake contraction, dynamic wake modulation, and meandering and deflection of nacelle wake, etc.) revealed by our snow-powered imaging techniques, and their connections with constantly-changing inflows and turbine operation, which are uniquely associated with utility-scale turbines. Additionally, we will talk about how such techniques has been used to probe into the flow structures and their organization in the atmospheric boundary layer as well as the variation of snow settling dynamics upon the changing turbulence and snow conditions in the field.
