About this Research Topic
The purpose of this Research Topic is to spread the latest research results in this field for both academia and industrial applications. The reduction of extreme and fatigue loads as well as the optimization of energy production are of great importance for enhancing the economic viability of wind energy projects. There are three independent variables that play a decisive role on the cost of energy (COE):
1) the energy captured by the turbine or the wind farm over its lifetime,
2) the operation and maintenance (O&M) expenses
3) the capital cost of the turbine.
The first and second points can be positively influenced by the use of control flow devices. In many cases, their use won‘t affect significantly the third point. Therefore, active and passive flow control devices can be very helpful to reduce the wind energy cost of energy.
This Research Topic is devoted to both active and passive flow control devices in wind turbines and aerodynamic upgrades for improving the performance of a single turbine as well a group of them. Contributions based on theoretical, experimental as well as numerical work will be considered for publication. The goal is to expand the body of knowledge of this field of aerodynamics and in this way contribute to the enhancement of wind turbine efficiency as well as to the optimization of the economic feasibility of wind energy projects.
