Abstract


Abstract: This paper continues the optimization of a new classical Darrieus rotor. After determining the geometrical characteristics of the new rotor, in this article has been passed to the analysis of torque, torque coefficient and rotor forces. The aim of the study is to investigate the efficiency or necessity of additional geometrical and aerodynamic changes on the torque and resultant rotor forces. Thus was investigated the addition of flaps to a part of the rotor. The study concludes that the torque variation in one turn can be improved by adding flaps.

Keywords: Vertical Axis Wind Turbine (VAWT), power curve, turbine torque, flaps.
