Abstract
This paper presents a flow visualization study of swept shock wave / turbulent boundary layer interactions using computer image processing technique in the supersonic flow at Mach number of 3.1. The test model is composed of a flat plate and sharp fins. Images obtained from oil-spot, liquid crystal coatings for surface shear force and vapor screen visualization were processed. Streaklines of oil spots are determined quantitatively by an active threshold selection method. By image processes of liquid crystal coatings for surface shear force and vapor screen, the spatial relation among shear stress distribution, separation lines and separation vortex is clarified. Surface pressure distribution is integrated into these processed images for comparison.
