Report Number: R16E0041 Responsible Representative: Soshi Kawai(Department of Aerospace Engineering, Tohoku University.) Contact Information: Soshi Kawai(kawai@cfd.mech.tohoku.ac.jp) Members: Hiroyuki Asada, Soshi Kawai Subject Category: Aviation(Body sound) Abstract Low-noise devices for reducing airframe noise of aircrafts have been studied and developed in many literature, but the details of interaction between each device are insufficiently investigated. This study develops discontinuous Galerkin (DG) based high-fidelity numerical schemes for compressible turbulent flows around aircrafts to enhance guidelines for designing next-generation low-noise aircrafts by clarifying the・・・<<read more>>
