title = "Direct Numerical Simulations of Hypersonic Boundary-Layer Transition for a Straight Cone at Mach 4: Oblique Breakdown",
abstract = "Direct Numerical Simulations (DNS) were carried out to investigate the laminar-turbulent transition process for a sharp straight (right) cone with a 7º opening half-angle at Mach 4 and zero angle of attack. A three-dimensional wave packet simulation indicated that the socalled oblique breakdown is the dominant nonlinear mechanism. A highly-resolved DNS of an oblique breakdown confirmed that the boundary layer breaks down rapidly towards turbulent flow when the transition process is initiated by a pair of oblique first mode disturbances. The boundary-layer transition process was simulated deep into the nonlinear transition regime and towards the development of a fully turbulent flow.",
