Introducing and Comparing Momentum Models in Aerodynamic Analysis of Vertical Axis Wind Turbine

Today, many countries are trying to reduce their dependence on fossil fuels and acquire the energy they need through renewable energy such as wind energy. On the other hand, the design and analysis of wind turbines is suitable for more energy one of the challenges of engineers. Therefore, in this study, momentum models, which is one of the basic methods in the aerodynamics modeling of the vertical axis wind turbine, are examined. These methods are based on the theory of the momentum (actuator disc) and are widely used to evaluate the performance of vertical axis wind turbines. Also it has been attempted to collect basic fair models for designing and analyzing the performance of these turbines. The following are the three models of the stream tubes: the SST model, the MST model, and the dual actuator MST or the same DMST. Each of these models has the advantages and disadvantages that are fully discussed in this research.
