Turbulence Modelling Applied to Aerodynamic Design
This paper presents the state of the art of the turbulence modelling at Dassault Aviation and the ability to compute complex flows of industrial interest. It describes developments performed to achieve an accurate and efficient simulation capacity, used as an engineering tool for aerodynamic design. The development is performed within an in-house code used at Dassault for the aerodynamic design of both military aircrafts and business jets. Non-exhaustive challenging industrial applications are presented, for which turbulence modelling improvements lead to a major impact on key design issues. RANS as well as Reynolds Stresses Models and LES/DES approaches will be assessed.
