RESUMO

The three-dimensional flow field structure in the area of reattachment of laminar-separated flow at a compression corner is considered. The Mach number of the free stream is M = 6. The model under consideration represents a plate with a sharp leading edge and a ramp installed at 30°. The model width is equal to the length of the plate from the leading edge to the ramp. The formation of streamwise near-wall vortices is discussed based on the results of analysis of the three-dimensional flow vortex structure in the area of reattachment.
