On the sources of cyclic loads in horizontal-axis wind turbines: The role of blade-section misalignment
(Pergamon-Elsevier Science Ltd, 2018-03)
In this paper we investigate the sources of cyclic loads affecting the structural solicitation and power production in Horizontal Axis Wind Turbines, in particular the role of blade-section misalignment. These loads could ...
Experimental analysis of biomimetic blades for small wind turbines
(Universidade Federal de UberlândiaBrasilEngenharia Aeronáutica, 2021)
Estudo aerodinâmico das pás de uma turbina eólica de eixo horizontal de pequeno porte utilizando o software QBlade
(Universidade Tecnológica Federal do ParanáLondrinaBrasilEngenharia MecânicaUTFPR, 2021-08-24)
This work presents a proposal for the aerodynamical study of a small horizontal axis wind turbine. The aerodynamic design is performed using Qblade, an opensource software, which performs calculations based on Betz limit ...
Aeromechanical evaluation of large HAWT’s blades
(2010-02)
This paper presents aeromechanical evaluation of a blade (length, 50 m) of horizontal axis wind turbines (HAWT). Aerodynamic module combines three-dimensional non-linear lifting surface theory approach and a two-dimensional ...
Otimização de perfis aerodinâmicos aplicados em aerogeradores do tipo TEEH utilizando algoritmo genético
(Universidade Federal do Rio Grande do NorteBrasilUFRNEngenharia Mecânica, 2021-05-04)
In Brazil, the search for the use of renewable sources to produce electric energy is growing and wind is a good alternative, as there is seasonal complementarity with water, contributing to the country's energy diversity. ...
Effects of rotor deformation in wind-turbine performance: The Dynamic Rotor Deformation Blade Element Momentum model (DRD-BEM)
(Pergamon-Elsevier Science Ltd, 2016-07)
Understanding the multi-physics phenomena associated with blade dynamics constitutes a fundamental factor for the continuous development of wind-turbine technology and the optimization of the efficiency of wind farms. Large ...
The adaptive-blade concept in wind-power applications
(Elsevier, 2014-10)
One of the technological challenges in wind power is the development of a next generation of feasible upscaled turbines of cheaper construction that may further reduce generation costs. But limitations in the current blade ...
