Abstract

Origin of the streaks is examined in the flat plate boundary layer at Mach 2. They arise due to the interaction of the weak shock waves with flow in vicinity of the flat plate leading edge. The process is accompanied by significant increase of the pulsation amplitudes in the boundary layer. The effect for the sharp leading edge is not so visible. The case of flat plate with blunted leading edge of 0.6 mm in radius is tested here. Results of the action of pair weak shock waves can be different and this finding is considered in the paper.
