We were delighted to have had Koen Boorsma from TNO present at the 5th Wind & Drivetrain Conference on April 6, 2022.
@KB is a Researcher at TNO, Netherlands. TNO connects people and knowledge to create innovations that boost the competitive strength of industry and the well-being of society in a sustainable way.
Koen's field of research focuses on numerical modeling and experimental analysis related to wind turbines, precisely field and wind tunnels.
Since 2008 he has developed unsteady aerodynamics and acoustic solvers to analyze wind turbines. In 2014 Koen coordinated the New Mexico experiment: A fully instrumented wind turbine model was tested in the largest wind tunnel of Europe, resulting in a database used worldwide in the wind energy community for model validation.
Koen has been active as a coordinator and contributor to international projects (IEA Task 29 and 47), EU projects (e.g., EU AVATAR, INNWIND, IRPWind), national research projects, and as an industry consultant.
Koen has worked as a reviewer for several international journals, conferences, and national and international project proposals. Further, Koen has been an advisor to Master and Ph.D. students.
Abstract:
A growing demand for clean energy has pushed further development of wind energy concepts. Conventional horizontal axis wind turbines (HAWTs) have grown taller with large and flexible blades. Offshore wind energy has been given a boost, where floating concepts are starting to make their way into the market. In the light of the above-mentioned developments, vertical axis wind turbines (VAWTs) have received renewed interest due to their low center of gravity combined with a good upscaling perspective.
All of the mentioned developments involve challenges in their dynamic modeling. Low computational cost methods are necessary to resolve the dynamic load envelope to perform fast design iterations but with sufficient accuracy. Some of the modeling efforts at TNO to progress these challenges are highlighted in the current presentation.
Validation of rotor aerodynamic models for HAWTs using a field aerodynamic database with detailed measurements is highlighted. A novel implementation of the blade element momentum (BEM) method to account for floater motions is illustrated. Lastly, aero-elastic modeling of a vertical axis wind turbine concept is under investigation.
