Darrieus type vertical axis wind turbine (VAWT) design

The book "Darrieus type vertical axis wind turbine (VAWT) design" offers a comprehensive analysis aimed at improving the performance of vertical wind turbines (VAWT). It addresses the efficiency and operational range of these turbines and presents the results of an experimental investigation into various rotor blade shapes. By utilizing measuring instruments and mathematical formulas, different values for the torque ratio (TSR), power coefficient (Cp), and turbine speed ratio (Vt) are determined. The authors compare the performance of seven rotors to identify the optimal model. The goal is to determine the power coefficient as a function of turbine speed and to find the best cross-sectional profile for the Darrieus turbine. The authors hope that this type of turbine will become economically viable and competitive with other energy conversion technologies in the future, particularly due to its ease of maintenance and installation.
