Rotational CARS for simultaneous measurements of temperature and concentrations of N-2, O-2, CO, and CO2 demonstrated in a CO/air diffusion flame

Vestin, Fredrik LU and Bengtsson, Per-Erik LU orcid (2009) In Proceedings of the Combustion Institute 32. p.847-854
Abstract
Rotational coherent anti-Stokes Raman spectroscopy (CARS) has over the years demonstrated its strong potential to measure temperature and relative concentrations of major species in combustion. A recent work is the development and experimental validation of a CO2 model for thermometry, in addition to our previous rotational CARS models for other molecules. In the,present work, additional calibration measurements for relative CO2/N-2 concentrations have been made in the temperature range 294-1246 K in standardized CO2/N-2 mixtures. Following these calibration measurements, rotational CARS measurements were performed in a laminar CO/air diffusion flame stabilized on a Wolfhard-Parker burner. High-quality spectra were recorded from the... (More)

In the,present work, additional calibration measurements for relative CO2/N-2 concentrations have been made in the temperature range 294-1246 K in standardized CO2/N-2 mixtures. Following these calibration measurements, rotational CARS measurements were performed in a laminar CO/air diffusion flame stabilized on a Wolfhard-Parker burner. High-quality spectra were recorded from the fuel-rich region to the surrounding hot air in a lateral cross section of the flame. The spectra were evaluated to obtain simultaneous profiles of temperature and concentrations of all major species; N-2, O-2, CO, and CO2. The potential for rotational CARS as a multi-species detection technique is discussed in relation to corresponding strategies for vibrational CARS, (c) 2009 The Combustion institute.
