“…Rich low pressure flames. Very similar benzene flames at low pressures (25-40 mbar) with U = 1.78-2 have been studied by many different groups using different experimental techniques [33,35,37,38].…”

“…These data are particularly useful because they provide more detailed isomer identification. Finally, the structure of similar rich flames (U = 2) at 45-50 mbar was measured using two different techniqu es: gas chromatography [38] and MBMS [35]. The experime ntal conditions of each flame are summarized in Table 4.…”

“…Table 1 summarizes the experimental data relating to benzene. These include well-stirred [16][17][18][19] and flow reactors [14,[20][21][22] at different operating pressures, shock tubes [19,[23][24][25][26][27][28], rapid compression machines [29], batch reactors [30], burner stabilized flames, as well as counterflow and spherically expanding flames [3,[31][32][33][34][35][36][37][38][39]. Figure 1 shows an axonometri c view of the wide range of analyzed experimental temperature , pressure and equivalence ratio condition s, with the related bi-dimensiona l sections.…”

“…Whereas experimental investigations of such benzene flames have been carried out by a few groups [4][5][6][7][8], they only concern rich benzene flames with equivalence ratios of 1.8 and 2. The pioneering works of Bittner and Howard [4] have been used for the development of many detailed kinetic mechanisms [9][10][11][12][13][14][15][16].…”

One-dimensional laminar premixed benzene-oxygen-argon flames with equivalence ratios of 2, 1, and 0.7, stabilized at low pressure (45 mbar) on a flat flame burner are studied. Gas sampling is performed by a conical quartz nozzle, at different positions in the flames. Identification and monitoring of chemical species is performed by gas chromatography. These measurements should complete experimental data on rich and sooting benzene flames available in the literature and will be of particular help for further improvements of benzene oxidation mechanisms. A comparison of experimental results with data simulated with the use of two recent kinetic models highlights their inability to predict stoichiometric and lean benzene combustion.

“…Additional experimental and modeling activities are still required to confirm this point. Recent studies in rich premixed laminar flames increase the amount of data available for mechanism validations [68][69][70]. More importantly, however, new mass spectrometric studies, performed with photoionization using monochromated synchrotron radiation, constitute a marked progress in elaboration of detailed analytical databases.…”

From the very first experimental studies, based essentially on flame propagation velocity and flame emission measurements, successive improvements in analytical and numerical techniques have contributed to make the analysis of laminar flame structure a powerful tool for extending the knowledge on combustion chemistry, thermodynamics, and transport properties. This better knowledge is very beneficial to design efficient combustion devices with reduced pollutant emission. Overall net species production rates are derived from the experimental determination of the evolution of the gas stream velocity, temperature, and species concentrations in the direction normal to the flame front. For species involved in a limited number of reactions, rate constants can be calculated at the next step. The development, in the early 1980s, of numerical codes for simulating the structure of one-dimensional laminar premixed flames the flame structure data to be directly used for validating detailed reaction mechanisms. Species analyses are still performed with techniques based on local gas sampling by probes, despite flame perturbations, but flame structure analyses have been markedly enriched by the use of non-intrusive spectroscopic techniques. The former allow the analysis of a large variety of species, and they have proven to be very well adapted to the large number of intermediate species formed in rich flames or in flames fed by heavy fuel molecules. The molecular beam mass spectrometry technique has been recently improved by the use of new photoionization sources that allow identification of isomers and extend the knowledge on intermediate species involved in formation ofbenzene, polycyclic aromatic hydrocarbons, and soot in flames. Amongst various spectroscopic techniques applied to flame structure analyses, laser-induced fluorescence has been largely used to perform accurate quantitative measurements of intermediate radicals that play a key role in the prompt-NO mechanism. In this study, the contribution of flame structure studies to a better knowledge of formation mechanisms of benzene and NO x is briefly reviewed.
