In the work, the aerodynamic characteristics of the Darrieus wind turbine with hollow blades were obtained by numerical CFD modeling and compared with the aerodynamic characteristics of the Darrieus wind turbine with solid blades. The H-rotor with hollow blades cannot be used at rotational speeds smaller than the nominal one, because of the non-linearity of the frequency characteristic of the torque (curve with two maxima and two minima).

摘要

In the work, the aerodynamic characteristics of the Darrieus wind turbine with hollow blades were obtained by numerical CFD modeling and compared with the aerodynamic characteristics of the Darrieus wind turbine with solid blades. The H-rotor with hollow blades cannot be used at rotational speeds smaller than the nominal one, because of the non-linearity of the frequency characteristic of the torque (curve with two maxima and two minima).
