Onset of wake meandering for a floating offshore wind turbine under side-to-side motion [PDF]

open access: yesJournal of Fluid Mechanics, 2021
Wind turbine wakes, being convectively unstable, may behave as an amplifier of upstream perturbations and make downstream turbines experience strong inflow fluctuations.

Vortex structure behind highly heated tandem twin cylinders

open access: yesNihon Kikai Gakkai ronbunshu, 2022
Vortex structures behind two highly heated cylinders of equal diameter in tandem arrangements have been investigated experimentally. The experiments were performed under the following conditions: cylinders diameter, D = 4 mm; mean flow velocity of air, U∞

Wake Width: Discussion of Several Methods How to Estimate It by Using Measured Experimental Data

open access: yesEnergies, 2021
Several methods of defining and estimating the width of a turbulent wake are presented and tested on the experimental data obtained in the wake past an asymmetric prismatic airfoil NACA 64(3)-618, which is often used as tip profile of the wind turbines ...

Control-oriented model for secondary effects of wake steering

open access: yes, 2021
. This paper presents a model to incorporate the secondary effects of wake steering in large arrays of turbines. Previous models have focused on the aerodynamic interaction of wake steering between two turbines. The model proposed in this paper builds on

L’Œil du cyclone

open access: yesFrancosphères, 2023
This article probes the convergence of meteorological disaster and memory in L’Île et une nuit by Daniel Maximin and La Case du commandeur by Édouard Glissant, reading fragments of these novels through reflections lifted from spiritual autobiographies by

WMLES of flows around small-scale propellers - estimating aerodynamic performance and wake visualization [PDF]

open access: yesTheoretical and Applied Mechanics, 2023
Wall-modeled large-eddy simulation (WMLES) is an advanced mathematical model for turbulent flows which solves for the low-pass filtered numerical solution. A subgrid-scale (SGS) model is used to account for the effects of unresolved small-scale turbulent

Results from a wake-steering experiment at a commercial wind plant: investigating the wind speed dependence of wake-steering performance

open access: yesWind Energy Science, 2021
. Wake steering is a wind farm control strategy in which upstream wind turbines are misaligned with the wind to redirect their wakes away from downstream turbines, thereby increasing the net wind plant power production and reducing fatigue loads ...

Research on the Power Capture and Wake Characteristics of a Wind Turbine Based on a Modified Actuator Line Model

open access: yesEnergies, 2022
On a wind farm, the wake has an important impact on the performance of the wind turbines. For example, the wake of an upstream wind turbine affects the blade load and output power of the downstream wind turbine.
