Optimizing a Straight‐Bladed Vertical Axis Wind Turbine With Computational Fluid Dynamics (CFD), Artificial Neural Network (ANN), and Genetic Algorithm (GA)

Energy Science &Engineering, Volume 13, Issue 12, Page 6003-6016, December 2025.
ABSTRACT Vertical axis wind turbine (VAWT) is a suitable renewable power generation tool for use in urban areas, especially at low wind speeds and with low noise level. However, an approach with accurate results, acceptable time consumption, and cost for optimizing this turbine is not reported in the literature.

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

Wind Energy, Volume 28, Issue 8, August 2025.
ABSTRACT 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 performance by modifying the rotor blade designs.

Meteorological Assessment of Vertical Axis Wind Turbine Energy Microgeneration Potentials Across Two Swiss Cities Located in Complex Terrain

Wind Energy, Volume 28, Issue 8, August 2025.
ABSTRACT Wind energy is the most mature renewable energy technology; however, its exploitation in cities is often met with skepticism. Thanks to their ability to operate at low wind speed regardless of direction, vertical axis wind turbines (VAWTs) offer an attractive opportunity for wind energy harvesting in cities. However, limited evidence exists on
