Development of Combustion Diagnostics and Application to Turbulent Combustion.
Abstract
Experiments have been conducted in steady, fluctuating and sooting flames produced in flat flame and slot burners operating on premixed fuel and air at atmospheric pressure. Measurements of temperature, CO species concentration and CO spectroscopic parameters have been made using a tunable diode laser absorption technique. The measurements involve rapidly scanning the narrow-linewidth diode laser across individual vibration-rotation lines in the fundamental band of CO at 4.6 microns to record fully-resolved absorption line profiles in times as short as 100 microseconds. A conventional microprobe sampling system to monitor CO and CO2 concentrations has been constructed to enable comparisons between laser-based and conventional measurements; thermocouples have been used to allow comparisons with laser-based temperature measurements. Initial results in fuel-rich flames show good agreement. Work is in progress to modify the burner system to allow comparisons over a wider range of stoichiometries.
