Journal ArticleDOI
Numerical investigation of conventional and modified Savonius wind turbines
TL;DR: In this article, the performance of a Savonius wind turbine with constant cross-sections is examined by means of quasi 2D flow predictions executed in ANSYS CFX, in a way that allows comparison with wind tunnel data presented in a related paper.
Journal ArticleDOI
Numerical investigations of an influence of the aspect ratio on the Savonius rotor performance
Journal ArticleDOI
Numerical Investigations of the Savonius Turbine with Deformable Blades
TL;DR: In this article, a new idea of the Savonius turbine with a variable geometry of blades is proposed, where the blades, made of elastic material, were continuously deformed during the rotor revolution to increase a positive torque of the advancing blade and to decrease a negative torque of returning blade.
Journal ArticleDOI
Computational assessment of the influence of the overlap ratio on the power characteristics of a Classical Savonius wind turbine
TL;DR: In this article, an influence of the overlap on the performance of the Savonius wind turbine was investigated and the maximum device performance was achieved for the buckets overlap ratio close to 0.
