Vertical wake deflection for floating wind turbines by differential ballast control [PDF]
, 2021 Abstract. This paper presents a feasibility analysis of vertical wake steering for floating turbines by differential ballast control. This new concept is based on the idea of pitching the floater with respect to the water surface, thereby achieving a desired tilt of the turbine rotor disk.

Wake Deflection Measurement in a Wind Tunnel with a Lidar WindScanner
, 2019 This presentation aims to provide a thorough understanding of the evolution of the wake at different inflow condition and operation condition, by measuring the the flow structures in the wake of a model turbine from 1D up to 10D downstream. The measurement campaign was conducted from May through June 2019 using the MoWiTO 0.6 wind turbine model in the ...

X-band crab cavities for the CLIC beam delivery system [PDF]
, 2008 The CLIC machine incorporates a 20 mrad crossing angle at the IP to aid the extraction of spent beams. In order to recover the luminosity lost through the crossing angle a crab cavity is proposed to rotate the bunches prior to collision.
