“…The ratio of the blade tip to wind speed is a comparative indicator for wind turbines. This ratio is approximately 7 for turbine blades with maximum lift power and 0.3 for blades with pressure drag [44][45][46] . Figure 2 shows a comparison between turbine efficiencies.…”

Increased concern for the environment has led to the search for more environment-friendly energy sources so that wind energy can be used as an endless option for human consumption. Wind turbines offer a promising solution for off-grid areas. However, they have certain drawbacks associated with different configurations. Darrieus turbine is one type that can be more efficient than other types. The poor start-up performance of Darrieus turbines is one of the critical problems restricting its development. Another problem of this kind of wind turbine is tackled by identifying the optimization parameters, such as complex flow dynamics around the system. The present article reviews modeling vertical axis turbines methods and discusses the turbine’s operation by presenting the results of these methods. In this review, the authors have attempted to compile the main aerodynamic models that have been used for performance prediction and design of straight-bladed Darrieus-type VAWT. The main object of this study is to research the advantages and disadvantages of wind turbine modeling methods, and the selection of these methods depends on the purpose of the modeling.
