Aerodynamics of wind turbines [PDF]

open access: yes, 2011
PhDThe study of rotor blade aerodynamic performances of wind tur- bine has been presented in this thesis. This study was focused on aero- dynamic effects changed by blade surface distribution as well as grid solution along the airfoil.

Research on the application of improved NSGA-II in the structure design of wind turbine blade spar cap

open access: yesFrontiers in Energy Research, 2023
Introduction: The blade is one of the most important parts of a wind turbine. Blade design is a complicated process involving many design links and mutual couplings.

EVOLUTIONARY DESIGN OF WIND TURBINE BLADES

open access: yesInternational Journal of Computing, 2014
An automatic design environment is implemented for the aerodynamic design of wind turbine blades. This tool involves the integration of evolutionary techniques and a simple, fast, and robust aerodynamic simulator which was developed for the prediction of the performance of any turbine blade produced by the evolutionary process.

Free-form design of rotor blades

open access: yesJournal of Physics: Conference Series, 2014
This work investigates an integrated free-form approach for the design of rotor blades, where airfoil shapes are treated as unknowns. This leads to the simultaneous optimization of the chord, twist and structural design variables, together with the airfoil shapes along the blade.

An Aerodynamic Optimization Approach for Wind Turbine Blades Using Proper Generalized Decomposition

open access: yesEnergies
A new approach for optimizing the blade profile of a horizontal axis wind turbine is proposed in this paper, based on the combination of the Blade Element Momentum (BEM) method and Proper Generalized Decomposition (PGD).

Leucine‐rich glioma inactivated 1 (LGI1) is a ganglioside‐binding protein

open access: yesFEBS Letters, EarlyView.
Neuronal hyperexcitability associated with a decrease/absence of the extracellular protein LGI1 has been suggested to be primarily due to the downregulation of Kv1 channel expression. The molecular mechanisms underlying this decrease have not yet been elucidated.

Effect of Air-Ducted Blade Design on Horizontal Axis Wind Turbine Performance

open access: yesEnergies, 2020
Wind turbines without pitch control are more preferable from economical point of view but aerodynamic stall affects them more and after a critical wind speed local boundary layer separation occurs.
