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

2D Numerical Simulation and Sensitive Analysis of H-Darrieus Wind Turbine
International Journal of Renewable Energy Development, 2018 Recently, a lot of attention has been devoted to the use of Darrieus wind turbines in urban areas. The aerodynamics of a Darrieus turbine are very complex due to dynamic stall and changing forces on the turbine triggered by changing horizontal angles. In

Wind Energy, Volume 28, Issue 2, February 2025.ABSTRACT Vertical‐axis wind turbines (VAWTs) operate in the atmospheric boundary layer and are frequently subjected to turbulent flow. The objective of this study is to investigate the effect of free‐stream turbulence on the power performance and wake characteristics of a pair of counter‐rotating VAWTs.
