- Abstract
- Progress in modelling combustion systems requires a data base that can be used to validate not only the shapes, locations, and magnitudes of species' concentration profiles, but also the local temperature. Traditionally, temperature measurements have been made with fine wire thermocouples which must be corrected for possible catalytic and radiative effects. These effects may be exasperated in flame regions that have an abundance of particulate matter. Tunable diode lasers have been shown to be effective tools for both species concentration and temperature measurements in combustion systems. In this paper, we will demonstrate their use for the determination of temperature and the concentration of carbon monoxide using both direct absorption and modulation techniques in a laminar diffusion flame. Comparison of these results with prior experimental work will be made.
