Cross-correlating blade--wake dynamics for a model wind turbine
Francisco J. G. de Oliveira, Zahra Sharif Khoadei, Oliver R. H. Buxton
Understanding how wakes interact with wind turbine blades under varying operating and inflow conditions is essential for improving fatigue prediction and performance assessment in…
Effect of freestream turbulence on the coherent dynamics of a wind turbine wake
Neelakash Biswas, Oliver R. H. Buxton
The wake of a model wind turbine exposed to incoming freestream turbulence (FST) with a variety of turbulent characteristics is studied through Particle Image Velocimetry experimen…
Wind-turbine wake effects on the rate of accumulation of fatigue damage in overhead conductors
Francisco J. G. de Oliveira, Kevin Gouder, Zahra Sharif Khodaei +1
Guidance relating to the safe distance within which overhead conductors (OHCs) should not be built with respect to a wind turbine, and vice versa, varies from country to country. I…
The effect of tip-speed ratio and free-stream turbulence on the coupled wind turbine blade/wake dynamics
Francisco J. G. de Oliveira, Martin Bourhis, Zahra Sharif Khodaei +1
Wind turbines operating within wind farms experience complex aerodynamic loading arising from the interplay between wake-induced velocity deficits, enhanced turbulence, and varying…
Computational and Experimental Comparison of CLF5605 and roamx-0201 Martian Helicopter Rotor Airfoils
Lidia Caros, Witold J. F. Koning, Takayuki Nagata +7
This study compares aerodynamic performance of the CLF5605 rotor airfoil -- which flew on Ingenuity from 2021 to 2024 -- with that of a new optimized roamx-0201 airfoil designed fo…
Impact of freestream turbulence and thrust coefficient on wind turbine-generated wakes
Martin Bourhis, Thomas Messmer, Michael Hölling +1
This study investigates how variations in freestream turbulence (FST) and the thrust coefficient () influence wind turbine wakes. Wakes generated at …
