abstract
The evolution of the large-scale density structure in a turbulent boundary layer at Mach 2.9 was studied using double-pulsed Rayleigh scattering. Pairs of images of the instantaneous density field ware obtained with time delays ranging from 12 sec to 60 sec, and they were used to determine qualitatively the changes in the structures as they move downstream. Instantaneous convection velocities were also measured.
