Turbulent flow regimes, compressible or otherwise, are omnipresent in high-Reynolds-number aerodynamic systems. Accurate prediction is required to anticipate and optimise the performance of new concepts. Optimisation is particularly important where the reduction of chemical and noise pollution is concerned. Robustness and safety for real weather and varying environmental conditions are also critical for aeronautical/terrestrial transportation and for renewable energy industries. These constraints have driven significant progress in the academic and industrial communities in recent years, for instance in the fields of Hybrid, Large-Eddy simulation and Lattice-Boltzmann approaches for the modelling and analysis of unsteady industrial flows; or in the development of measurement methodologies that are now frequently used in the context of data-driven modelling. New theoretical frameworks have appeared for the description of out-of-equilibrium turbulence, and for the reduction and modelling of coherent structures

55th 3AF International Conference

on Applied Aerodynamics

Turbulent flows in Aerodynamic Applications

Poitiers, France - April 12-13-14, 2021


TURBULENT FLOWS IN AERODYNAMIC APPLICATIONS

The 3AF International Conference on Applied Aerodynamics is an annual event organised by the French Aeronautics and Aerospace Society (3AF) at French venues known for their activity in the field of aeronautics and/or aerospace technology. The Conference is an excellent opportunity for scientific exchange between scientists from industry, research institutions and academia. Scientists and engineers from other fluid mechanics fields are also welcome.

Each year the Conference addresses a different topic in the field of aerodynamics. It is organised on the basis of five half- days of technical presentations, each introduced by a keynote conference given by a recognised expert. The Conference is concluded by a technical visit in connection with the conference subject.

In 2021, the Conference will be hosted by the Pprime Institute (CNRS, ISAE-ENSMA, University of Poitiers) in Poitiers. This 55th 3AF International Conference on Applied Aerodynamics (AERO2020+1) focuses on Turbulent flows in Aerodynamic Applications.

Turbulent flow regimes, compressible or otherwise, are omnipresent in high-Reynolds-number aerodynamic systems. Accurate prediction is required to anticipate and optimise the performance of new concepts. Optimisation is particularly important where the reduction of chemical and noise pollution is concerned. Robustness and safety for real weather and varying environmental conditions are also critical for aeronautical/terrestrial transportation and for renewable energy industries. These constraints have driven significant progress in the academic and industrial communities in recent years, for instance in the fields of Hybrid, Large-Eddy simulation and Lattice-Boltzmann approaches for the modelling and analysis of unsteady industrial flows; or in the development of measurement methodologies that are now frequently used in the context of data-driven modelling. New theoretical frameworks have appeared for the description of out-of-equilibrium turbulence, and for the reduction and modelling of coherent structures and their sound radiation. These frameworks provide a foundation for the development of flow-control strategies. The prediction of transition to turbulence in complex flows, particularly important in the aeronautical sector, is also an active domain.
