Повний текст джерелаThis work is focused on drag driven vertical axis wind turbines. The study involved both experimental measurements and numerical analyses. The two methods are complementary: CFD analyses allow us gain an insight into the rotor's fluid dynamics that lead to energy production. The experimental measurements allow us to evaluate the elements that are difficult to put inside a numerical model. For this reason the two approaches have different aims. The experiments have been performed in a closed circuit wind tunnel. They investigate the configurations that could improve the performance of a given rotor. The numerical analyses were conducted to improve the flow field knowledge and to design new rotor's geometries. Both approaches started from a classic Savonius rotor equipped with semi-circular straight blades S-shaped, with end plates to replicate the two-dimensional effects of the numerical model. The performance were evaluated with CP-lambda plots, where CP is the Power coefficient and lambda is the rotation velocity versus wind speed ratio. The best experimental configuration correspond to the reference rotor with conveyor and deflector: its CP max was 0.3, with +25% gain with the respect of the reference rotor. CFD analyses have shown two best geometries: the classical Savonius without the central shaft and a new geometry defined as “reversed profile”. They have both a CP maximum around 0.29 without any external appendices. Finally an external test station was build up to perform experimental measurements on full-scale small wind turbines models. It is composed by a test station for prototypes, a 10 meters meteorological mast and a Sodar-Rass station. It was found that the site is characterized by local breezes blowing most of the year and a prevailing direction of 330 degrees. The external station is operational and an urban lamppost prototype supplied by wind energy and is currently the subject of experimental studies.
