Abstract

Experimental work that gives a quantitative two-dimensional picture of the turbulent structure in supersonic boundary layers and free shear layers is reported. Oxygen flow tagging by Raman excitation plus laser-induced electronic fluorescence permits lines or points to be written into air and interrogated at a later time to generate quantitative pictures of instantaneous velocity profiles. The two-dimensional density cross section is generated by simultaneously recording the Rayleigh scattering. The experimental procedure is described, and results for an underexpanded supersonic jet with lines written through it at the Mach 3.6 location and for boundary layers are presented.
