  1. 1. Large Eddy Simulation for the Analysis of Jet Noise Suppression Devices

    Författare :Markus Olander Burak; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LES; Mixer-ejector; Aeroacoustics; CAA; Acoustic liner; Broadband time-domain impedance boundary condition;

    Sammanfattning : Stricter noise regulations for commercial aircraft have increased interest in noise reduction techniques within the aerospace industry. To meet the requirements new noise suppression technologies have to be delveoped and the numerical methods need to be validated and possibly improved for the correct assessment of these new technologies.
