Determination of The Optimal Parameters of a Vertical Axis Wind Turbine with Cylindrical Guide Vane Unit

This paper presents the results of an experimental study of a Darrieus type vertical wind turbine. The aerodynamic turbine scheme is made up of a classic runner and cylindrical guide vanes. The characteristics of the turbine have been investigated and the optimal values of three of the parameters have been determined with planned physical experiment: pitch angle of the working blades, pitch angle of the guide vanes and number of the guide vanes. The results of the experimental studies and the possibilities for improving the efficiency of the turbine are analyzed.
