The physics of H-Darrieus turbine starting behavior [PDF]

open access: yes, 2014
This paper provides a resolution to the contradictory accounts of whether or not the Darrieus turbine can self-start. The paper builds on previous work proposing an analogy between the aerofoil in Darrieus motion and flapping-wing flow mechanisms.

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

open access: yesWind 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.

Noise Emission of a 200 kW Vertical Axis Wind Turbine

open access: yesEnergies, 2015
The noise emission from a vertical axis wind turbine (VAWT) has been investigated. A noise measurement campaign on a 200 kW straight-bladed VAWT has been conducted, and the result has been compared to a semi-empirical model for turbulent-boundary-layer ...

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

open access: yesWind 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

Multi‐Rotor Systems: Can They Increase Economy‐Wide Benefits Compared to Traditional Designs?

open access: yesWind Energy, Volume 28, Issue 8, August 2025.
ABSTRACT This short communication reports on the economic consequences of increasing the market share of potentially lower‐cost offshore wind designs. We use data on the projected levelised cost of energy (LCOE) for traditional horizontal axis wind turbine (HAWT) designs compared with an illustrative multi‐rotor system which could have lower costs ...
