Development of a Stall Barrier with Internal Flow Channel for Effective, Highly Separated Boundary Layer and Flow Control in the Rotor Blade Root Region

Article Preview

Abstract:

As part of a cluster project in the Aerospace research cluster at the Hochschule Bremen, the model rotor blade of a wind turbine is to be aerodynamically optimized with a more effective stall barrier. The flow element to be developed should provide very effective interruption of the radial flow on the rotor blade. A combination of this flow element and the "Splitflap" flow element allows the aerodynamic efficiency of the rotor blade to be further improved.
