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 ∼3000 K with the spatial resolution of ∼0.04×0.04×2.5 mm3. The duration of a single measurement was 10 ns and the sampling rate was 10 Hz. The error of the temperature determination was ∼4% for the single-shot measurements and ∼0.15% for the measurements of the average values during 100 s under the quasi-stationary burning conditions.
