Design and analysis of a wake steering controller with wind direction variability [PDF]
Wind farm control strategies are being developed to mitigate wake losses in wind farms, increasing energy production. Wake steering is a type of wind farm control in which a wind turbine's yaw position is misaligned from the wind direction, causing its ...

Multi-model ensemble wake vortex prediction [PDF]
Purpose Wake vortices that are generated by an aircraft as a consequence of lift constitute a potential danger to the following aircraft. To predict and avoid dangerous situations, wake vortex transport and decay models have been developed. Being based on different model physics, they can complement each other with their individual strengths ...

Neighborhood Effects in Wind Farm Performance: A Regression Approach
The optimization of turbine density in wind farms entails a trade-off between the usage of scarce, expensive land and power losses through turbine wake effects.

Anisotropic double‐Gaussian analytical wake model for an isolated horizontal‐axis wind turbine
An anisotropic double Gaussian (DG) model for analytical wake modeling to predict the streamwise wake velocity behind an isolated non‐yawed horizontal‐axis wind turbine is proposed.

VELOCITY FIELD AROUND DARRIEUS WIND TURBINE ROTOR USING ACTUATOR CELL MODEL AND OTHER CFD METHODS
The main purpose of this work is to analyze the usefulness of the active cell model (ACM) developed by the author of this article to estimate the flow field around a single-bladed vertical-axis wind turbine (VAWT) with the Darrieus-type rotor.

Comparison of a coupled near- and far-wake model with a free-wake vortex code [PDF]
This paper presents the integration of a near-wake model for trailing vorticity, which is based on a prescribed-wake lifting-line model proposed by Beddoes(1987), with a blade element momentum (BEM)-based far-wake model and a 2-D shed vorticity model.
