Abstract

We report a technique that is capable of making simultaneous two-point time-series measurements of minor-species concentrations in turbulent flames. The experimental setup, which incorporates picosecond time-resolved laser-induced fluorescence, has a spatial resolution of less than $250\mu \mathrm{m}$ and a temporal resolution of less than $100\mu \mathrm{s}$, which spatially and temporally resolve microscales in many turbulent flows. Two-point time-series data are given for a standard turbulent nonpremixed flame at $\mathit{Re}=10,000$, including a discussion of potential implications.
