Abstract

The performance of small wind turbines at low wind speeds suffer from low Reynolds number aerodynamic effects limiting the energy harvesting capability of these class of machines. By using passive and semi-active flow control it is possible to delay static stall and reduce the severity of dynamic stall effects that degrade the performance of all small wind turbines, including Vertical Axis Wind Turbines (VAWT). Using separation control the power generation significantly increases at low winds.
