Abstract

Abstract

Through direct numerical simulation,the evolution of a 2-D disturbance in a supersonic boundary layer has been investigated.At a chosen location,a small amplitude T-S wave was fed into the boundary layer to investigate its evolution.Characteristics of non-linear evolution have been found.Two methods were applied for the detection of shocklels,and it was found that when the amplitude of the disturbance reached a certain value,shocklets would be generated,which should be taken into consideration when non-linear theory of hydrodynamic stability for compressible flows is to be estabfished.
