Evolution of a stall vortex over an external dihedral corner in a supersonic flow

  • Published:
Thermophysics and Aeromechanics Aims and scope

Abstract

The work is devoted to the study of a vortex system formed in a flow past a streamwise-aligned external dihedral corner due to the drop of pressure between the corner faces. A detailed comparison of experimental and calculated data on the visualization of the flow and on the distribution of pressure over the model surface obtained at Mach number M∞ = 2.27 in the range of angles of attack α = 0–20° is reported.
