Abstract

Detailed flow visualization experiments were carried out in a self-similar turbulent mixing layer at a nominal convective Mach number of 1.1. The flow visualization technique was base on Rayleigh scattering from nanometer-scale contaminant particles present in the freestream flow. The interface marked by the vaporization of the particles revealed the large-scale organized turbulence structures in the mixing layer. Quantitative measures of the length scale, orientation, and speed of organized structures were derived from the flow visualization data, and were found to agree well with conventional point-probe measurements.
