Joukowski’s wake model for tip-splitting rotors [PDF]
Journal of Physics: Conference Series, 2021 Abstract The interaction between a tip vortex and a solid surface is responsible for premature structural component fatigue in wind turbines and undesirable noise in helicopter rotors during low speed and descending flight. One noise reduction strategy uses a modified airfoil to split and spread the vorticity in two tip vortices.

Layout Optimization of a Modular Floating Wind Farm Based on the Full-Field Wake Model
Energies, 2022 By optimizing the positions of wind turbines in a wind farm, the power loss caused by wake effects can be reduced maximally. A new methodology of layout optimization is proposed utilizing a full-field wake model that integrates the near-field and far ...

International Journal of Renewable Energy Development, 2022 The objective of this paper is to investigate the ability of analytical wake models to estimate the wake effects between wind turbines (WTs). The interaction of multiple wakes reduces the total power output produced by a large offshore wind farm (LOFWF).

Multi-model ensemble wake vortex prediction [PDF]
Aircraft Engineering and Aerospace Technology, 2016 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 ...

Generalized coupled wake boundary layer model: applications and comparisons with field and LES data for two wind-farms [PDF]
, 2016 We describe a generalization of the Coupled Wake Boundary Layer (CWBL) model for wind-farms that can be used to evaluate the performance of wind-farms under arbitrary wind inflow directions whereas the original CWBL model (Stevens et al., J.
