Optimal tuning of engineering wake models through lidar measurements [PDF]
Wind Energy Science, 2020 Engineering wake models provide the invaluable advantage to predict wind turbine wakes, power capture, and, in turn, annual energy production for an entire wind farm with very low computational costs compared to higher-fidelity numerical tools.

High-resolution CFD modelling of Lillgrund Wind farm [PDF]
, 2013 We report on a fully dynamic simulation of Vattenfall’s Lillgrund offshore Wind Farm, with a focus on the wake effects of turbines on the performance of individual turbines, and of the farm as a whole.The model uses a dynamic representation of a wind ...

On the Wind Turbine Wake Mathematical Modelling
Energy Procedia, 2018 Abstract The present paper deals with a study on the wind turbine wake mathematical modelling as well as experimental validation by means of wind tunnel experiments. In particular, different wind turbine wake’s equations were implemented and results compared with experimental data.

Leading effect for wind turbine wake models
Renewable Energy, 2023 As wind energy expands worldwide, the demand of reliable, fast, cost-efficient wind turbine wake models is growing. This is a significant challenge as wind turbines face various inflow conditions, that include turbulence, inhomogeneities/instationarities and upstream wakes.

Etude numérique et expérimentale de l'écoulement autour d'un rotor éolien [PDF]
, 2013 An improved model of an actuator surface is proposed, representing the flow around a wind turbine. This model was developed in conjunction with a Navier-Stokes solver using a blade element method for the calculation of power and wake development.

Bidirectional wakes over complex terrain using SCADA data and wake models [PDF]
Wind Energy ScienceWe investigate bidirectional wake effects between two wind turbines of the same type in a hill region in northern Japan using supervisory control and data acquisition (SCADA) data and validate the simulated wakes using 12 wake models. The extent to which

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.

Field Measurements of Wind Turbine Wakes with Lidars [PDF]
Journal of Atmospheric and Oceanic Technology, 2013 AbstractField measurements of the wake flow produced from a 2-MW Enercon E-70 wind turbine were performed using three scanning Doppler wind lidars. A GPS-based technique was used to determine the position of the wind turbine and the wind lidar locations, as well as the direction of the laser beams.
