title = "Numerical study of the effects of cooling on evolution of unsteady disturbances and transition to turbulence in a boundary layer at flow mach number M = 6",
abstract = "Direct Numerical Simulation (DNS) is used to investigate linear and nonlinear stages of development of unstable disturbances and the transition to turbulence in a supersonic boundary layer on a flat plate with the Mach number of the external flow M = 6. The computations are carried out for the case of a cooled surface at a ratio of the plate temperature to the free-stream temperature Tw/T∞ = 1.4. According to linear stability theory calculations, the two-dimensional waves of the first mode in the boundary layer are completely stabilized at the considered flow parameters. The growth rates are maximum for unstable two-dimensional disturbances of the second mode, while the three-dimensional waves of the second mode are also unstable. The results of DNS of linear and nonlinear stages of development of such disturbances are compared with the results of earlier computations of the laminar-turbulent transition on a flat plate with a temperature corresponding to the case of a thermally insulated surface, Tw/T∞ = 7.",
