Abstract

This paper addresses the interpretation of a flow visualization technique based on Rayleigh scattering from nanometer-scale contaminant particles in a turbulent boundary layer flow and a turbulent mixing layer flow at a Mach number of 2.9. The interface marked by the scattering particles reveals large-scale organized turbulence structures in the two flows. Quantitative measures of the scale, orientation, and speed of the structures have been extracted from the data, and have been found to compare well with conventional point probe measurements. These results indicate that the technique accurately portrays many of the physical features of the two flows.
