Résumé

The paper introduces basic principles of two techniques to estimate soot volume fraction and temperature in reactive media. They are based on specific measurements of radiation emission by the flame and on appropriate modeling of the corresponding spectra involving the participating gaseous species and soot particles. The first approach uses narrow band emission by carbon dioxide to get the local temperature. The second one employs wide band emission by soot particles so as to estimate their local volume fraction. Fundamentals of those techniques are given and applied for the inversion of simulated and/or experimental data.
