Abstract The H-Darrieus wind turbine could be applied as an alternative electricity generation source. However, their performance is still low, affecting less attention to being used as electricity generation ...sources. Considering the current condition, the present study provides a numerical simulation of a potential performance enhancement of the H-Darrieus wind turbine by adding a high-efficiency vortex (HEV). HEV owns the ability to control the flow around the blade. HEV causes turbulent flow around the turbine while increasing turbulent kinetic energy. Three different HEV structures in rectangular, trapezoidal, and triangular shapes were attached to the blade to investigate the wind turbine performance. Two-tab angles (β) of 30° and 45° were applied to each structure to investigate the best position of HEV. The blade without HEV was considered as the baseline for the performance evaluation. It is revealed that triangular HEV performed the best with β of 30°, improving the power coefficient by 34% compared to the baseline when the tip speed ratio (TSR) is more than 1.5.show more
