Assessing the impact of waves and platform dynamics on floating wind-turbine energy production

Autor: A. Fontanella, G. Colpani, M. De Pascali, S. Muggiasca, M. Belloli

Publikováno v: Wind Energy Science, Vol 9, Pp 1393-1417 (2024)

Waves have the potential to increase the power output of a floating wind turbine by forcing its rotor to move against the wind. Starting from this observation, we use four multi-physics models of increasing complexity to investigate the role of waves

Controller design for model-scale rotors and validation using prescribed motion

Autor: A. Fontanella, E. Daka, F. Novais, M. Belloli

Publikováno v: Wind Energy Science, Vol 8, Pp 1351-1368 (2023)

Aerodynamic-load calculation in aero-hydro-servo-elastic modeling tools has been recently validated against experiments for low-frequency platform motions but without considering the capability of active wind turbine controls. This work presents a co

Wind tunnel investigation of the aerodynamic response of two 15 MW floating wind turbines

Autor: A. Fontanella, A. Facchinetti, S. Di Carlo, M. Belloli

Publikováno v: Wind Energy Science, Vol 7, Pp 1711-1729 (2022)

The aerodynamics of floating turbines is complicated by large motions which are permitted by the floating foundation, and the interaction between turbine, wind, and wake is not yet fully understood. The object of this paper is a wind tunnel campaign

UNAFLOW: a holistic wind tunnel experiment about the aerodynamic response of floating wind turbines under imposed surge motion

Autor: A. Fontanella, I. Bayati, R. Mikkelsen, M. Belloli, A. Zasso

Publikováno v: Wind Energy Science, Vol 6, Pp 1169-1190 (2021)

Floating offshore wind turbines are subjected to large motions due to the additional degrees of freedom of the floating foundation. The turbine rotor often operates in highly dynamic inflow conditions, and this has a significant effect on the overall

Model-based design of a wave-feedforward control strategy in floating wind turbines

Autor: A. Fontanella, M. Al, J.-W. van Wingerden, M. Belloli

Publikováno v: Wind Energy Science, Vol 6, Pp 885-901 (2021)

Floating wind turbines rely on feedback-only control strategies to mitigate the negative effects of wave excitation. Improved power generation and lower fatigue loads can be achieved by including information about incoming waves in the turbine contro

Geometry of massless scattering in integrable superstring

Autor: A. Fontanella, A. Torrielli

Publikováno v: Journal of High Energy Physics, Vol 2019, Iss 6, Pp 1-34 (2019)

Abstract We consider the action of the q-deformed Poincaré superalgebra on the massless non-relativistic R-matrix in ordinary (undeformed) integrable AdS 2 × S 2 × T 6 type IIB superstring theory. The boost generator acts non-trivially on the R-ma
