title = "Numerical Investigations of the Nonlinear Stages of Hypersonic Boundary-Layer Transition for an Ogive Geometry",
abstract = "Numerical investigations were carried out for the boundary layer of an ogive geometry with a blunted nose tip and for the flow conditions of the German Aerospace Center (DLR) hypersonic wind tunnel (H2K) experiments at Mach 5.3. Linear Stability Theory (LST) analysis identified amplified first- and second-mode waves. Various nonlinear transition scenarios were examined using Direct Numerical Simulations (DNS). The simulation results for a “controlled” first mode oblique breakdown showed a transition development in the boundary layer advancing towards the late nonlinear stages and turbulence, with oblique first-mode waves initiating transition. The forcing amplitudes were selected to align the transition onset in simulations with that observed in experiments.",
