Computational Aeroacoustics, III 


Date:  4th - 5th June 2018

Location: ONERA, Paris, France

Coordinators: Prof Christophe Bailly, Ecole Centrale de Lyon, France 

Organiser:  ERCOFTAC 

ERCOFTAC is proud to announce the third course on Computational Aeroacoustics.

This course is intended for researchers in industry and in academia including Ph.D. Students with a good knowledge in fluid mechanics, who would like to build up or widen their knowledge in the field of aeroacoustics (modeling, computational tools and industrial applications). It will first provide a comprehensive overview of recent insights of aeroacoustics theories (Lighthill’s analogy and vortex sound theory, extensive hybrid approaches and wave extrapolation methods, duct acoustics). A number of practical problems involving the coupling between CFD’s results and CAA will be also thoroughly discussed (e.g. how design a mesh size for aeroacoustics applications using large eddy simulation, inclusion of mean flow effects via hybrid formulations such as the acoustic perturbation equations, presence of surfaces, aeroacoustic couplings, …) and realistic applications performed by the instructors (aeronautics, car industry, propulsion, energy,…) will be discussed. Advanced computational aeroacoustics methods will be also presented as well as what we can learn from the direct computation of aerodynamic noise. Finally, specific topics reflecting participant interests will be discussed in a final round table session.
