A Study of a Darrieus Vertical Axis Wind Turbine with a guiding nozzle

This paper presents the results from an experimental study of a Vertical Axis Wind turbine model with a guiding nozzle. The geometry of the nozzle is synthesized by an original methodology. The performance characteristics of the turbine are investigated when changing the number of the blades and the...
