Method for Calculating Rotors with Active Gurney Flaps [PDF]
Journal of Aircraft, 2016 This paper builds on the Helicopter Multi-Block version 2 computational-fluid-dynamics solver of the University of Liverpool and demonstrates the implementation and use of Gurney flaps on wings and rotors. The idea is to flag any cell face within the computational mesh with a solid, no-slip boundary condition.

Optimum design of morphing flaps for improving horizontal axis wind turbine performance
Energy Science &Engineering, Volume 11, Issue 7, Page 2431-2443, July 2023., 2023 This study presents a conceptual design of optimum deformable wind turbine blades as a function of wind speed. The WindPACT 1.5‐MW wind turbine is used as the base turbine, which has three different sections at the root, middle, and tip of the blade. The computational fluid dynamics results show that using optimum flap angles between 2° and 8° in the ...

Wind Energy, Volume 26, Issue 7, Page 668-690, July 2023., 2023 Abstract An operating 2‐MW wind turbine has been scanned and analysed using 2D computational fluid dynamics (CFD) and blade element momentum (BEM) analysis. The current work illustrates using full‐scale 3D CFD simulations the differences between 2D and 3D simulations and its impact on the local aerofoil vortex shedding frequency. The outcome shows that
