The subharmonic transition process of a flat plate boundary layer at a free-stream Mach number of M∞ =4.5 is investigated by direct numerical simulation up to laminar breakdown. An explicit spectral/ finite-difference scheme employing the temporal model is used. A second-mode instability is forced initially, superimposed with random noise of low amplitude. The secondary subharmonic instability evolves in accordance with theory and leads to a staggered A-vortex pattern. Finite-amplitude A-vortices initiate the buildup of detached high-shear layers. Two levels of subsequent shear-layer roll-up have been observed.
