Flow accelerator for wind power installations with the vertical rotation axis

The article presents a research aimed at determining the hub geometric parameters enabling maximum of the air flow acceleration. In the course of the research work different installations were investigated — from simple to complex structures — in order to analyze the necessity of making certain parts of the accelerator more complicated and modernized, as well as to obtain optimal geometry of the structure. Also the paper presents the results of simulation and experimental studies of the tower type air flow vortex accelerator.
