Abstract
A technique for the simultaneous measurements of the instantaneous concentrations of two species being mixed in a turbulent flow is developed using a combined laser‐induced fluorescence and laser‐scattering technique, and the quantitative measurements are demonstrated in a simple grid‐generated turbulent flow with two streams of nonpremixed species. It is shown that the present technique enables one to measure simultaneously the instantaneous concentrations of two species with spatial and time resolutions far less than the Kolmogorov length and time scales.Keywords
