Abstract

Presented here are broadband, dual-pump CARS measurements which were performed in a 2-meter diameter methanol pool fire. Single-shot temperature and relative mole fractions were obtained simultaneously. The temperatures were compared to traditional thermocouple measurements in the pool fire. It was found that the CARS mean temperatures agree to within 4% of the thermocouple measurements, while the RMS temperatures were an order of magnitude less for the thermocouple. The accuracy and precision of the single-shot temperature measurements were characterized by comparison to a laboratory standard. It was determined that between 500-1400 K the CARS instrument was accurate to better than 4% and the measurements were reproducible to within 6%.
