Aerodynamic Design (AER)

The Section for Aerodynamic Design focuses on aerodynamic and aeroacoustic research based on modelling and experimental techniques. 

The research in AER deals with fidelities ranging from engineering aerodynamic modelling to vortex-based and Computational Fluid Dynamics (CFD), facilitating fluid-structure coupling for high-fidelity aerodynamic and aeroelastic analysis as well as multidisciplinary design.

Our focus is on the continuous development and refinement of the design basis for existing and new concepts with a view to enhance the design process and reduce uncertainties, as well as on the development and application of systems engineering tools—considering the complexity associated with upscaling, advanced control, and lightweight structures.

The tools and knowledge are applied in interaction with the wind industry in the design process for solving design problems or implementing new design concepts such as, e.g., lightweight blades, two-bladed wind turbines, and distributed blade censoring and control. Flap control technology is an important subject at the moment and has been developed in close cooperation with the wind turbine industry. A project to move the technology to the next readiness level is ongoing. Also, design of the layout of aerodynamic devices and leading edge roughness caused by, e.g., erosion are important aspects. 

A main focus is on extending the aerodynamic and aeroacoustic design methods with advanced models to support the development of rotors with very high capacity factors (>60%).
In connection with the new Poul la Cour Wind Tunnel at DTU, aeroacoustic measurement methods and models and high Reynolds number aerodynamics are being developed. The Poul la Cour Wind Tunnel, the DTU Research Turbine, and The Rotating Test Rig are expected to offer a tremendous boost in our capabilities to increase the impact of our innovation in, e.g., design tools, airfoils, and smart blades, and are expected to lead to new creative aerodynamic solutions.
