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

The use of urban and rural scale wind turbines that in addition to generating power can play the role of old wind turbines in arid areas will be very attractive. In this research it has been tried to first evaluate the wind energy potential in Zahedan city and then to evaluate a sample of vertical axis wind turbine. First, a three-dimensional semi-analytic code based on the DMST method was developed, the validation of which was studied and presented. Using this tool, the performance of the turbine in terms of power and ventilation has been investigated and in the results of this parametric study, the effect of the cone angle on the power and ventilation coefficient has been explained in detail. Based on the results of this study, it can be seen that increasing the cone angle to ۲۰ degrees, although it reduces the power of the turbine, but does not have a significant effect on the power coefficient and at the same time causes a ventilation coefficient of about ۱.۶ percent. It was also observed that at a conical angle of ۱۰ degrees and at the working point of the turbine, the output power will be ۳۰ kW and the ventilation flow will be ۳۰,۰۰۰ m^۳⁄h.
