Abstract

The propagation of the disturbance waves in a boundary layer at Mach number=4.5 is studied by direct numerical simulation(DNS),using NND scheme,and different amplitudes A=0.01,0.001,0.000 1 of the disturbance have been assumed.The numerical result shows that there might be shocklets induced in the boundary layer,even when the amplitude of disturbance wave is still small.

- shocklet,
