 note = {Spatial direct numerical simulations are used to study the formation and development of three-dimensional structures in a compressible flat plate boundary layer, where the freestream Mach number is 0.5 and the Reynolds number at the inlet based on the displacement thickness 1,000. A pair of stable oblique modes and a two-dimensional unstable T-S wave are 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 of the freestream value. Oblique modes with the TS wave produces peak-valley splitting downstream and later hairpin vortices (hairpin packet) on the low speed streak are observed. So-called subharmonic transition appears downstream in the boundary layer. DNS results show that the forming hairpin packet is responsible for sound waves emission., 資料番号: AA0049212028, レポート番号: JAXA-SP-05-017},
