Controlled aerodynamic instability phenomena

The term controlled aerodynamic instability phenomena was first used by Cristiano Augusto Trein in the Nineteenth KKCNN Symposium on Civil Engineering held in Kyoto, Japan, in 2006. The concept is based on the idea that aerodynamic instability phenomena, such as Kármán vortex street, flutter, galloping and buffeting, can be driven into a controlled motion and be used to extract energy from the flow, becoming an alternative approach for wind power generation systems.
