Darrieus Vertical Axis Wind Turbine (VAWT) Performance Enhancement by Means of Gurney Flap
MachinesThis study investigates the aerodynamic effect of Gurney flaps (GFs) of different heights on the performance of a Darrieus vertical axis wind turbine (VAWT). Through numerical simulations, the performance of a baseline airfoil is compared against configurations with GFs of 0.5%c, 1%c, and 1.5%c chord lengths across a range of tip-speed ratios (TSRs ...

A novel small vertical axis wind turbine using delta-wing blades
, 2014 We present a novel Vertical Axis Wind Turbine (VAWT) that uses flat delta-wings instead of aerodynamically shaped blades with airfoil cross-sections. This choice lowers the manufacturing costs significantly.
