Ferreira, Carlos (author), Yu, W. (author), Sala, A. (author), Viré, A.C. (author)Floating offshore wind turbines may experience large surge motions, which can cause blade–vortex interaction if they are similar to or faster than the local wind speed. Previous research hypothesized that this blade–vortex interaction phenomenon represented a turbulent wake state or even a vortex ring state, rendering the actuator disc momentum...journal article 2022

De Tavernier, D. (author), Ferreira, Carlos (author), Viré, A.C. (author), LeBlanc, B.P. (author), Bernardy, S. (author)Vortex generators (VGs) have proven their capabilities in wind turbine applications to delay stall in steady flow conditions. However, their behaviour in unsteady conditions is insufficiently understood. This paper presents an experimental study that demonstrates the effect of VGs in unsteady flow, including controlling and suppressing the...journal article 2021

De Tavernier, D. (author), Viré, A.C. (author), Ferreira, Carlos (author)In this work, we demonstrate to what extent it is possible to use load optimisation to aerodynamically damp the floater motion of vertical-axis wind turbines. The loadform of a VAWT can be altered to the desired objective using an individual blade-pitch schedule. A coupled hydro- and aerodynamic simulation tool is built solving the equation...journal article 2020

Dong, J. (author), Viré, A.C. (author), Ferreira, Carlos (author), Li, Zhangrui (author), van Bussel, G.J.W. (author)A modified free-wake vortex ring model is proposed to compute the dynamics of a floating horizontal-axis wind turbine, which is divided into two parts. The near wake model uses a blade bound vortex model and trailed vortex model, which is developed based on vortex filament method with straight lifting lines assumption. By contrast, the far...journal article 2019
