Abstract

Vibrational thermally assisted fluorescence of OH is used to obtain averaged two-dimensional temperature data from a lean methane-air flame. A simple two-level vibrational model is used to describe the relationship between the population ratio of excited states and temperature. The quenching versus vibrational transfer ratio between the excited states is used as a calibration parameter to fit the data to thermocouple measurements. This work in progress has yielded promising results, with temperatures typically within 100K of thermocouple data.
