Measurements of temperature spatial distribution and fluctuations in a hydrogen-oxygen flame at high pressures by means of coherent anti-Stokes Raman spectroscopy
Annotation
The results of measurements of the temperature field in a hydrogen-oxygen flame by means of the broadband coherent anti-Stokes Raman spectroscopy are presented. The measurements were performed at pressures up to $1.7$ MPa and temperatures $\sim 3000$ K with the spatial resolution of $\sim 0.04 \times 0.04 \times 2.5$ mm$^3$. The duration of a single measurement was $10$ ns and the sampling rate was $10$ Hz. The error of the temperature determination was $\sim 4\%$ for the single-shot measurements and $\sim 0.15\%$ for the measurements of the average values during $100$ s under the quasi-stationary burning conditions.
