Organizers:

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 (modelling, computational tools and industrial applications).

It will provide:

• a comprehensive overview of aeroacoustic theories (Lighthill analogy and vortex sound theory, FWH analogy, hybrid approaches, wave extrapolation methods, duct acoustics);
• the issues of the direct computation of aerodynamic noise using CFD methods (Large Eddy Simulation, Lattice-Boltzmann Method).

It will be discussed:

• a number of practical problems involving the coupling between CFD and CAA (e.g. how design a mesh size for aeroacoustics applications, inclusion of mean flow effects via hybrid formulations such as the acoustic perturbation equations, presence of surfaces, aero-acoustic couplings);
• realistic applications performed by the instructors (aeronautics, car industry, propulsion, energy);
• advanced computational aeroacoustics methods, as well as what we can learn from the direct computation of aerodynamic noise, will be presented;
• specific topics reflecting participant interests.

Lecturers:

• Dr Christophe Bogey, Ecole Centrale de Lyon, France, christophe.bogey@ec-lyon.fr
• Pr Gwenael Gabard, LAUM, Le Mans Université, France
• Dr Alois Sengissen, Airbus Avions, France
• Pr Stefan Schoder, TU Graz, Austria, stefan.schoder@tugraz.at
• Pr Wolfgang Schröder, Institute of Aerodynamics, Aachen, Germany
