Potential of Wake Scaling Techniques for Vertical-Axis Wind Turbine Wake Prediction

Energies
Analytical wake models are widely used to predict wind turbine wakes. While these models are well-established for horizontal-axis wind turbines (HAWTs), the analytical wake models for vertical-axis wind turbines (VAWTs) remain under-explored in the wind ...

Qualification of three analytical wake models

, 2015
Les pertes de sillage sont généralement quantifiées à l'aide des modèles analytiques caractérisant le sillage. La puissance totale estimée du parc éolien varie en fonction de la fiabilité du modèle utilisé. Cet article qualifie la performance des trois modèles analytiques (Jensen,Ishihara et Frandsen) pour prédire la vitesse du vent dans la zone du ...

Prediction of contra-rotating open rotor broadband noise in isolated and installed configurations

, 2014
Broadband noise is a significant part of the noise emitted by contra-rotating open rotors. Several noise sources can contribute to the total broadband sound field, with the most dominant ones probably being trailing edge noise, rotor-wake interaction ...

DETERMINATION OF WAKE SHAPES BEHIND A WIND TURBINE THROUGH CFD SIMULATIONS AND COMPARISON WITH ANALYTICAL WAKE MODELS

, 2021
In this paper, wake shapes of wind turbine rotors are investigated by using CFD and analytical wake models. The flow around the NTNU model turbine is simulated using the Reynolds-Averaged Navier-Stokes Equations with Spalart-Allmaras, standard k-epsilon,

Theoretical study of analytical wake models for yawed wind turbines

The present study will explore some of the most relevant engineering wake models for yawed wind turbines developed to date. Compared to wind tunnel tests and numerical simulations, analytical wake models have greater applications in real wind farm ...

A diffusion-based wind turbine wake model

Describing the evolution of a wind turbine's wake from a top-hat profile near the turbine to a Gaussian profile in the far wake is a central feature of many engineering wake models.
