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 ...
Effects of urban configuration on the wind energy distribution over a building
(Amer Inst Physics, 2015)
A numerical study to investigate the wind energy potential for various building configurations is
presented. Steady-state incompressible flow simulations were performed using the finite volume
method of ANSYS Fluent with ...

A nonlinear and non-ideal wind generator supporting structure
(Trans Tech Publications Ltd, 2006-01-01)
We present a simple mathematical model of a wind turbine supporting tower. Here, the wind excitation is considered to be a non-ideal power source. In such a consideration, there is interaction between the energy supply and ...
Feasibility of the use of wind energy generation at sewage plants in Montevideo city
(UR. FING, 2000)
Due to environmental concerns, the Montevideo City authorities funded a feasibility study of the use of wind turbines in several sewage works. The generators, 150 kW or more each one, will be connected to the grid. The ...
A PLL-based resampling technique for vibration analysis in variable-speed wind turbines with PMSG: A bearing fault case
(Academic Press Ltd - Elsevier Science Ltd, 2017-02)
Condition monitoring in permanent magnet synchronous machines has gained interest due to the increasing use in applications such as electric traction and power generation. Particularly in wind power generation, non-invasive ...
Otimização estrutural de pás de turbinas eólicas de material compósito via funções de base radial
(Universidade Tecnológica Federal do ParanáCuritibaBrasilPrograma de Pós-Graduação em Engenharia Mecânica e de MateriaisUTFPR, 2021-02-26)
Wind turbines are machines capable of transforming wind kinetic energy into electricity. The turbine blades are responsible for converting aerodynamic forces into torque for the generator. In most cases, blades are made ...
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 ...
Structural analysis of wind-turbine blades by a generalized Timoshenko beam model
(American Society of Mechanical Engineers, 2010-02)
An important aspect in wind-turbine technology nowadays is to reduce the uncertainties related to blade dynamics by the improvement of the quality of numerical simulations of the fluid-structure interaction process. A ...
