Mie Scattering and Laser-Induced Fluorescence Measurements of Scalar Mixing in Compressible Free Shear Layers,

Abstract

The scalar transport characteristics of compressible mixing layers at two flow conditions have been investigated using both Mie scattering and laser-induced fluorescence. Large ensembles of two-dimensional digital images were collected and scalar probability density functions were computed. The Mie scattering visualizations employed condensed ethanol droplets while nitric oxide was utilized for the laser-induced fluorescence studies. For the cases considered, the mixing layer thermodynamic conditions are found to be an important factor in the relative agreement of the scalar transport measurements using the Mie scattering and laser-induced fluorescence techniques
