The evaluation of the performance of a Darrieus Vertical Axis Wind Turbine is performed using an actuator line code. This allows to investigate the aerodynamics of the turbine and the interaction with the boundary conditions. Blade Pitch control, tip-effects modelling and blockage effects in an open-jet wind tunnel test section are studied and investigated. Pitch control allows to enhance the power extraction, tip effects allow to generate a more realistic model, while the modelling of the open-jet test section allows to validate the numerical approach on experimental data intrinsically characterized by not negligible blockage effects.

Pitch control allows to enhance the power extraction, tip effects allow to generate a more realistic model, while the modelling of the open-jet test section allows to validate the numerical approach on experimental data intrinsically characterized by not negligible blockage effects.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
