Optimisation of the Aerodynamic Characteristics of H-Darrieus Vertical-axis Wind Turbines

This article presents a study of the aerodynamic characteristics of a small H-Darrieus wind turbine to optimise its design. The article proposes correlations between the blades' geometric and aerodynamic characteristics, optimising the blades' profile and their dimensions for various values of wind speed, aerodynamic forces, and rotational moments. The data obtained can be helpful in the design and study of low-power wind turbines operating at low wind speeds with variable directions.
