Dissipation scaling in wind turbine wakes exposed to free-stream turbulence
Martin Bourhis, Oliver R. H. Buxton
The nature of the dissipation of turbulent kinetic energy (TKE) is investigated experimentally in the wake of a diameter m wind turbine exposed to several ``flavours'' of h…
Inter-turbine spacing and flow unsteadiness effects on wake-induced blade dynamics
Francisco J. G. de Oliveira, Adrian T. McGlade, Zahra Sharif Khodaei +1
Wind turbines operating downstream of others in a farm are routinely exposed to waked inflow, with reduced mean velocity and elevated turbulence driving power deficits and addition…
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…
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…
