Applications Of The 3.4Μm Laser Absorption Technique For The Study Of High Temperature Pyrolysis And Ignition Of Various Hydrocarbon Fuels

Abstract

The line of sight laser absorption diagnostics in shock tube experiments for detecting combustion species is a valuable tool for studying kinetics of chemical reactions. Methane is an important byproduct during the pyrolysis and ignition of higher order hydrocarbons. In the present study, shock tube and a continuous wave distributed feedback interband cascade laser (DFB ICL) were used for measurements of the absorption cross sections as well as concentration time-histories of methane and propanal at two wavelengths λpeak = 3403.4 nm and λvalley = 3403.7 nm. The empirically obtained absorption cross section correlations were utilized to demonstrate concentration time-histories of methane obtained during pyrolysis of various hydrocarbon fuels. The results were compared to the predictions of various kinetic mechanisms: GRI 3.0, Aramco 1.3, POLIMI, and NUIG mechanisms.
