 note = {Results from viscous linear stability analysis and DNS are presented for Mc = 1.17 and Mc = 1.55 plane jets. The linear stability analysis shows that there are A1 modes (antisymmetric modes) that the phase velocities are higher than the ambient sound speed including most unstable two dimensional one. On the other hand, the phase velocity of most unstable A1 3-D mode is less than the ambient speed of sound. The result of 2-D DNS shows that the amplification of a 2-D A1 mode generates strong Mach waves. In the 3-D DNS with A1 oblique modes that have a crucial effect of flow three-dimensionality, but without A1 2-D mode, the strong Mach waves disappear. These results suggest that early decrease of the jet centerline velocity caused by an A1 3-D mode restrained the strong Mach wave emission., 資料番号: AA0045947017, レポート番号: NAL SP-56},
