Enhanced Aerodynamic Performance of Savonius Wind Turbines Through Blade Design Modifications: A CFD Study

Wind Energy
The conventional Savonius wind turbine's power coefficient is comparatively low, which limits its efficiency. Because the power coefficient depends significantly on the blade design, this study investigates the potential of improving the turbine ...

CFD investigation on wind power harvesting from small-scale wind turbines for powering residential buildings in New Zealand. [PDF]

J R Soc N Z
ABSTRACT As an alternative solution, wind power could be harnessed by designing and implementing small‐scale wind turbines for distributed power generation. In this work, 3‐dimensional time‐domain numerical simulations, based on the Reynolds‐Average Navier‐Strokes (RANS) model, are conducted for two categories of small‐scale wind turbines, i.e.

CFD computation of the Savonius rotor

Journal of Theoretical and Applied Mechanics, 2015
In this paper, Computational Fluid Dynamics (CFD) analysis of a two-dimensional two- -bucket Savonius rotor, using ANSYS Fluent solver, is presented. Computational methods of fluid dynamics are used to estimate the aerodynamic forces acting on the rotor, the torque and the power extracted by the Savonius rotor.
