Multiphysics approach in Aerodynamics

53rd 3AF International conference on applied aerodynamics (AERO2018)

Abderrahmane Baïri,  Jean Délery, Bruno Chanetz

The 3AF-International Conference on Applied Aerodynamics is organized each year by the French Aeronautics and Astronautics Society (3AF) in a different venue in France known for its activities in the field of aeronautics and/or space technology. The conference is an excellent opportunity for scientific exchanges within the aerospace community where aerodynamicists from industry, research institutions and academia meet. Scientists and engineers from other fields involving fluid mechanics are also welcome.

Every year the conference addresses a different topic trending in the field of aerodynamics. It is organized on the basis of five half-day of technical presentations, each introduced by a keynote conference given by a highly recognized expert in the field covered during the session. The conference is concluded by a technical visit in connection with the conference subject.

In 2018, the conference was hosted by the French Air Force Academy at Salon-de-Provence and dealt with the subject Multiphysics approach in Aerodynamics 

This 53rd 3AF-International Conference on Applied Aerodynamics was aimed at bringing together a diverse range of disciplines, which have strong coupling with aerodynamics during design and optimisation. Aerodynamics remains one of the major design driver in aerospace and the overall transportation industry, but the way the industry has reshaped recently has urged us to consider a multi-physics approach in order to address environmental and sustainability issues, and open up new frontiers in hypersonic speed journeys. This also has the added benefit of reducing the number of design iterations and shortening the design cycle. Therefore deeper knowledge of the multidisciplinary field such as fluid and structure interaction, acoustic, thermodynamics, heat transfer and many others is required. This conference was a platform for researchers from a diverse range of disciplines to get together and discuss the challenges that the aerodynamics community currently faces, while finding common ground encouraging further collaborations.

Among the many aspects of the problem, the following items were considered: fluid/structure interaction and aeroelasticity, aeroacoustics and aero-thermo-acoustics, aerothermal and heat transfer, water droplet impingement, ice accretion and lightning strikes, multiphase flows, multidisciplinary optimization (MDO), measurement techniques and data acquisition (optics, electronics, etc.)

This special issue of the International Journal of Numerical Methods for Heat & Fluid Flow presents a selection of articles based on the most instructive contributions to the conference AERO2018.
