 note = {Spatial direct numerical simulations are performed to study the formation and development of three-dimensional structures in a compressible flat plate boundary layer, where the free-stream Mach number is 0.5 and the Reynolds number at the inlet based on the displacement thickness 1,000. A pair of neutral/stable oblique modes and a TS wave is superimposed on the laminar profile at the inlet plane of the boundary layer computational box. The magnitudes of the disturbances are chosen to be 1 percent or 0.5 percent of the free-stream value. After saturation of the T-S wave, the oblique modes produce peak-valley splitting downstream and hairpin vortices (hairpin packet) on the low speed streak are observed further downstream. So-called sub-harmonic transition appears downstream in the boundary layer. The numerical results show that the details of three-dimensional structure depend on the magnitude of the disturbance., 資料番号: AA0049208003, レポート番号: JAXA-SP-05-012},
