    Abstract
  • The initial disturbance combinations were selected based on the linear stability theory （LST） for a supersonic flat-plate boundary layer with Mach number of 4.5.Through direct numerical simulation （DNS），the generation process of streamwise vortex due to the evolution of combined first-mode unstable waves along the flow direction was simulated.Based on the vortex identification method of modified Omega-Liutex and the streamline diagram at different positions in the streamwise direction，the generation characteristics of streamwise vortex were analyzed，and its generation conditions were proposed according to the features of streamline in zy plane.It was found that streamwise vortex can be obtained directly by superimposing a pair of first-mode unstable oblique waves and basic flow，in which nonlinear action was not necessary.
