Localization and aerodynamic improvement of an urban-scale vertical axis wind turbine With respect to the climate of Sistan

The use of wind turbines on the urban and rural scale with the desired ventilation while producing power will be of great appeal. This study has attempted to assess the potential of wind energy in Zahedan and then evaluate the performance of a V-rotor turbine. For this purpose, using the 3D semi-analytical method is based on the Double Multiple Stream tube Method (DMST). Using this method, the performance of the turbine has been evaluated in terms of power and ventilation and the effect of the conical angle on power and ventilation has been studied parametrically. According to the results of this study, it can be seen that increasing the conical angle by up to 20 degrees, while reducing the power of the turbine, will not have a significant effect on the power coefficient. It is also observed that at 10 degrees conical angle and the turbine working point, the 30 KW output power and 10,000 𝑚􀬷⁄ℎ ventilation discharge will be obtained. Therefore, the 10-degree conical angle can be determined as a suitable angle for producing power and acceptable ventilation in the city s climatic conditions.
