3D CFD Simulation of a H-Darrieus Turbine with Variable Pitch: A Quantitative Vorticity Analysis

Vortices and dynamic stall play a critical role in the performance of vertical-axis wind turbines, often leading to significant energy losses. Active and passive control strategies can be employed to delay the dynamic stall, particularly at low tip-speed ratios below 0.5. In this study, three-dimensional Computational...
