Temperature measurements in spray flames by spontaneous Raman scattering. Academic Article uri icon

abstract

  • Spontaneous Raman scattering was applied for quantitative temperature measurements in turbulent methanol spray flames. Possible interferences from laser-induced breakdown and elastic light scattered from the fuel drops were discriminated against by optoacoustic means. Polycyclic aromatic hydrocarbons were found to be a negligible source of fluorescence interference. The capability of measuring the probability-density function of temperature in a turbulent nonsooting spray flame with an accuracy of +/-75 K was demonstrated. The technique appears simpler and less expensive than other spectroscopic approaches.
