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 ...
Study of the effect of the geometrical parameters of the runner and operation conditions on performance and flow characteristics in a cross flow turbine
(Universidad EAFITMaestría en IngenieríaEscuela de Ingeniería, 2014)
Due to technological development, massive use of technology, and accelerated population growth in some regions of the planet, the use of renewable energy sources is important to match the increasing electric energy demand ...

The search for and use of renewable energy sources has shown a great growth in recent years, and the development of a distributed microgeneration and its challenges. On this bias, the present work brings a proposal of a ...
A metamodel-based optimization approach to reduce the weight of composite laminated wind turbine blades
(Elsevier, 2018-06)
In wind turbine blades, the complex resultant geometry due to the aerodynamic design cannot be modified in the successive mechanical design stage. Hence, the reduction of the weight and manufacturing costs of the blades ...
Polynomial Chaos-Kriging metamodel for quantification of the debonding area in large wind turbine blades
(2021-01-01)
This study aims to investigate the performance of a data-driven methodology for quantifying damage based on the use of a metamodel obtained from the Polynomial Chaos-Kriging method. The investigation seeks to quantify the ...
Structural dynamic analysis of vertical bars of turbine protection trashracks of hydroelectric plant
(2016-01-01)
Trashracks of hydroelectric plants are very important equipment because they are responsible for protection of hydraulic turbines against impact of floating bodies. These structures are basically constituted by horizontal ...
Numerical simulations of active flow control with synthetic jets in a Darrieus turbine
(Elsevier, 2017-12)
This study presents two-dimensional numerical simulations of the flow around a cross-flow vertical-axis water turbine (straight-bladed Darrieus type) using active flow control by means of synthetic jets. The performance ...
