Startup Dynamics of Drag-Based Multibladed Vertical Axis Wind Turbine
Engineering ProceedingsA multibladed drag-based Vertical Axis Wind Turbine (VAWT) was developed and its startup dynamics evaluated using wind tunnel tests. The experimental data obtained for the time-based angular position of the rotor shaft at Aberdeen’s average wind speed of

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

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 ...

Darrieus Vertical Axis Wind Turbine (VAWT) Performance Enhancement by Means of Gurney Flap
MachinesThis study investigates the aerodynamic effect of Gurney flaps (GFs) of different heights on the performance of a Darrieus vertical axis wind turbine (VAWT). Through numerical simulations, the performance of a baseline airfoil is compared against configurations with GFs of 0.5%c, 1%c, and 1.5%c chord lengths across a range of tip-speed ratios (TSRs ...
