A 2d-Numerical Study on Slot Jet Applied to a Wind Turbine as a Circulation Control Technique
Petracci, Ivano; Manni, Luca; Angelino, Matteo; Corasaniti, Sandra; Gori, Fabio (Conference)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 ... -
