Large-Eddy Simulation of Wakes of Waked Wind Turbines
Energies, 2022 The wake dynamics of a wind turbine are influenced by the atmospheric turbulence and the wake of its upwind turbine. In this work, we investigate the wake characteristics of a waked wind turbine for four different downwind spacings and three different ...

Investigation of wind turbine flow and wake [PDF]
Journal of Fluid Science and Technology, 2014 This paper is dedicated to the investigation and analysis of wind turbine wake. An experimental work is undertaken in wind tunnel on a horizontal axis wind turbine model. The velocity field in the wake is measured using PIV with phase synchronization in order to relate velocity and vortices to the rotating blades.

The Importance of Wake Meandering on Wind Turbine Fatigue Loads in Wake [PDF]
Energies, 2021 Considering loads when optimizing wind-farm layouts or designing farm-control strategies is important, but the computational cost of using high-fidelity wake models in the loop can be prohibitively high. Using simpler models that consider only the spatial variation of turbulence statistics is a tempting alternative, but the accuracy of these models ...

Multirotor wind turbine wakes [PDF]
Physics of Fluids, 2019 To fulfill the increasing need for large power generation by wind turbines, the concept of multirotor wind turbines has recently received attention as a promising alternative to conventional massive single-rotor wind turbines. To shed light on the viability of this concept, large-eddy simulation is employed in this study to compare wake flow properties
