von Karman Institute for Fluid Dynamics
The von Karman Institute for Fluid Dynamics is a non-profit international educational and scientific organisation, hosting three departments: aeronautics and aerospace, environmental and applied fluid dynamics, and turbomachinery & propulsion. What began as an experiment in international postgraduate training in 1956 has developed into a widely recognized center of excellence in fluid dynamics, combining education and research into “training in research through research” in a truly international and intercultural environment. In this respect, the von Karman Institute, true to its visionary founder, occupies today a unique place in between the academic and the industrial world. The synergy between high level education and fundamental and applied research creates knowledge and value to the benefit of the students, the researchers, the faculty and the customers be it from industry or government research labs.

The H2020 UPWARDS project funded by the European Commission (no 763990) aims at improving wind turbine design by accounting for more realistic weather conditions, impacting both the generation of noise and its propagation through the atmospheric boundary layer.
The von Karman Institute for Fluid Dynamics (VKI) and Siemens Industry Software N.V. (SISW) are collaborating on that topic, and have reached an important milestone of the UPWARDS project, validating the core methods of the aeroacoustic simulation chain through benchmark comparison. The procedure is based on an automated two-dimensional workflow applied to iso-radius sections along the blade span. The VKI model is based on semi-empirical models derived from Amiet's theory while the method adopted by SISW is based on a stochastic reconstruction of sound sources combined with a finite-element code for acoustic propagation. Preliminary results have also been obtained for a Siemens SWT-2.3MW-93 wind turbine subjected to uniform flow conditions, as a first step. The next objectives are to account for real atmospheric boundary layer effects, and to include leading-edge noise due to incoming turbulence.

The video of the public PhD Defense of Fernando Miró Miró entitled "Numerical Investigation of Hypersonic Boundary Layer Stability and Transition in the presence of Ablation Phenomena" is available on the VKI Youtube Channel: https://youtu.be/MR-dAq4C6Ps
He presented the work he has carried out over the past years at the von Karman Institute and the Université Libre de Bruxelles, under the supervision of Fabio Pinna and Gérard Degrez. His research focused on hypersonic boundary-layer stability and transition in the presence of ablation phenomena, investigated from a numerical perspective, using linear stability theory. The jury unanimously agreed to grant Fernando the title of Doctor in Engineering Sciences and Technology (Docteur en Sciences de l’Ingénieur et Technologie). #VKI #ULB #ablation #boundarylayer #doctoralthesis #hypersonic
