(Aero) Acoustics and Aerodynamics

The (aero)acoustics and aerodynamics team focuses on solving societal and environmental issues with fundamental solutions. We aim for new, quantitative and qualitative understanding of the underlying phenomena to improve state-of-the-art methodologies, modeling and designing systems. The vision is to bridge the gap between academic knowledge and its actual application to societal and environmental issues that lead towards a sustainable and healthier society.

Active Research Projects


    zEPHYR has the following objectives:

    1. Foster a training-through-research network of young researchers, where the ESR fellows will investigate and further develop promising emerging technologies enabling a more efficient harvesting of wind energy resources in ‘conventional’ on-shore as well as urban environments through more accurate and robust simulation methodologies, supported by laboratory experiments and theoretical models, and applying novel optimization approaches.
    2. Bring in a coordinated research environment top-rank academia, research centres and industrial stakeholders, actively involved in top-level research in the fields of fluid dynamics, aeroacoustics, structural dynamics and fatigue life prediction, Uncertainty Quantification, optimization methods, system dynamics and control, and human factors.
    3. Offer an unprecedented training infrastructure where the young researchers will not only acquire the necessary scientific skills, but will also be confronted with the intricacies of an innovation process including integration, manufacturing, economical constraints, through strong interactions with the industrial world.

    Two on-shore application areas will be considered:
    i) horizontal axis wind turbines (HAWTs) with sizes corresponding to the current state-of-the-art (~ 5-10 MW), and
    ii) urban wind turbines, with a focus on the most promising concepts for urban integration such as vertical axis wind turbines (VAWTs), diffuser-augmented wind turbines (DAWTs) and building-integrated wind turbines (BIWTs).

    The noise and greenhouse gas emissions generated by aircraft have a negative impact on human health and the environment. To reduce noise and gaseous emissions, the EU-funded ENODISE project aims at improving the integration of novel aircraft’s propulsion systems with the airframe. To achieve this, it will study the key propulsion-airframe integration issues and build a solid basis of knowledge and methods. The project will investigate integration optima using a novel experimental methodology combined with high-fidelity simulations and low-order modelling approaches. It will also implement shape modifications and innovative flow/acoustic control technologies to maximise aero-propulsive efficiency while reducing adverse installation effects. The proposed research plan should lead to better integration designs with minimal detrimental installation effects.
