| الوصف: | International audience ; SNCF (Société Nationale des Chemins de Fer franc̃ais), PSA (Peugeot Citroën), EDF (Electricité de France) and ECL (Ecole Centrale de Lyon) are involved in a common project whose issue is the potential evaluation of numerical simulation in aeroacoustics for transport applications. One of the methods chosen in the project consists in the calculation of the aeroacoustic source term through a Large Eddy Simulation (LES) and its implementation into a code based on the Linearized Euler's Equations for the acoustic propagation (LEE). This paper presents a comparison of LES and experimental results of the aerodynamic field around a forward-backward facing step and the principle of the chain-up of LES results and LEE calculations. |
