Abstract
The file attached to this record is the author's final peer reviewed version.A study on the feasibility of the Circulation Control
(CC) technique for wind turbines is proposed. The
CC was born in aeronautic field to improve the lift
force on the wings, allowing the short take-off and
landing of aircraft. It consists in blowing air at a
relatively high speed over a rounded trailing edge.
The thin jet of air remains attached to the convex
curved surface, imposing a certain curvature to the
outer streamlines, and, hence, increasing the lift force
of the airfoil. Aim of this study is to numerically
investigate the advantages on a wind turbine, based
on the S809 airfoil, taking into account the energy related
considerations, as the cost of the jet
production. The paper, after a thorough evaluation of
the increase of the generated power, finds that this
technique could be promising in the energy harvesting
aim
