Experimental Study on Influence of Pitch Motion on the Wake of a Floating Wind Turbine Model
Energies, 2014 Wind tunnel experiments were performed, where the development of the wake of a model wind turbine was measured using stereo Particle Image Velocimetry to observe the influence of platform pitch motion.

Towards a Simplified DynamicWake Model Using POD Analysis
Energies, 2015 We apply a modified proper orthogonal decomposition (POD) to large eddy simulation data of a wind turbine wake in a turbulent atmospheric boundary layer. The turbine is modeled as an actuator disk.

Numerical investigation of wind turbine wakes under high thrust coefficient
Wind Energy, 2022 We study wind turbine wakes of rotors operating at high thrust coefficients (CT > 24/25) using large‐eddy simulations with a rotating actuator disk model. Wind turbine wakes at high thrust coefficients are different from wakes at low thrust coefficients.

MH-REACH-Mote: supporting multi-hop passive radio wake-up for wireless sensor network [PDF]
, 2015 A passive wake-up radio in a wireless sensor network (WSN) has the advantage of increasing network lifetime by using a wake-up radio receiver (WuRx) to eliminate unnecessary idle listening.

Biological activity in the wake of an island close to a coastal upwelling [PDF]
, 2008 Hydrodynamic forcing plays an important role in shaping the dynamics of marine organisms, in particular of plankton. In this work we study the planktonic biological activity in the wake of an island which is close to an upwelling region.

The cool wake around 4C 34.16 as seen by XMM-Newton [PDF]
, 2005 We present XMM-Newton observations of the wake-radiogalaxy system 4C34.16, which shows a cool and dense wake trailing behind 4C34.16's host galaxy. A comparison with numerical simulations is enlightening, as they demonstrate that the wake is produced ...

Fluidic force and wake velocity of 3D body with four limbs in uniform flow
Journal of Fluid Science and Technology, 2023 Robots that operate at a disaster site have been proposed and the dispatch of rescue robots to such site is required. However, discussion on the transport of these robots is insufficient.
