Curled-Skewed Wakes behind Yawed Wind Turbines Subject to Veered Inflow
Energies, 2022 This work presents a new engineering analytical model that predicts the effect of both the turbine yaw misalignment and the inflow wind veer on the wake flow distribution downwind of a wind turbine.

Simulation of wind turbine wake interaction using the vorticity transport model [PDF]
, 2010 The aerodynamic interactions that can occur within a wind farm can result in the constituent turbines generating a lower power output than would be possible if each of the turbines were operated in isolation.

Wind tunnel experiments on wind turbine wakes in yaw: Redefining the wake width [PDF]
Wind Energy Science, 2018 Abstract. This paper presents an investigation of wakes behind model wind turbines, including cases of yaw misalignment. Two different turbines were used and their wakes are compared, isolating effects of boundary conditions and turbine specifications. Laser Doppler Anemometry was used to scan a full plane of a wake normal to the main fow direction, 6 ...

Coupled wake boundary layer model of wind-farms [PDF]
, 2015 We present and test the coupled wake boundary layer (CWBL) model that describes the distribution of the power output in a wind-farm. The model couples the traditional, industry-standard wake model approach with a "top-down" model for the overall wind ...

Journal of Physics: Conference Series, 2015 A team of researchers from the National Renewable Energy Laboratory and Statoil used large-eddy simulations to numerically investigate the merging wakes from upstream offshore wind turbines. Merging wakes are typical phenomena in wind farm flows in which neighboring turbine wakes consolidate to form complex flow patterns that are as yet not well ...

Interaction of an Eulerian flue gas plume with wind turbines [PDF]
, 2010 The reduced availability of sites with the requisite wind resource, planning permission and public acceptance for the placement of wind turbines poses a significant challenge to future expansion of the wind energy industry.

Wake Management in Wind Farms: An Adaptive Control Approach
Energies, 2019 Advanced wind measuring systems like Light Detection and Ranging (LiDAR) is useful for wake management in wind farms. However, due to uncertainty in estimating the parameters involved, adaptive control of wake center is needed for a wind farm layout ...

Experimental study on the characteristics of wind turbine wake field considering yaw conditions
Energy Science & Engineering, 2021 This paper explores the wake of a wind turbine yaw and its influence on the output power of the downstream wind turbine. A wind turbine model (hub height and diameter of 1.2 m and 1.0 m, respectively) was used in the experiments, and the yaw angle of the

Wind shear estimation and wake detection by rotor loads - First wind tunnel verification [PDF]
, 2016 The paper describes a simple method for detecting presence and location of a wake affecting a downstream wind turbine operating in a wind power plant. First, the local wind speed and shear experienced by the wind turbine are estimated by the use of rotor
