Investigation of combustion enhancement by ozone additive in CH4/air flames using direct laminar burning velocity measurements and kinetic simulations

The effects of hydrodynamic stretch on the flame propagation enhancement of ethylene by addition of ozone

“…The chemical kinetic mechanism of USC Mech II [31] was used because of successful comparisons to experiments in a previous study [28]. Twenty-six O 3 reactions from [19,20,22] were added to the mechanism and are shown in table 1. As mentioned above, it was confirmed experimentally that O 3 does not react with the fuel prior to the combustion zone.…”

Plasma assisted combustion: kinetic studies and new combustion technology

“…Fig. 9 Comparison of simulated results (HP-Mech/plasma and GRI Mech 3.0 with an updated O3 mechanism by Konnov and coworkers [29]) with experimental results for burning velocity enhancement by ozone as a function of equivalence ratios 27…”

On the role of excited species in hydrogen combustion

“…It was demonstrated [34] that due to the incompleteness of the MSU mechanism (absence of many reverse reactions) it predicts an incorrect balance between O atoms, excited and ground state oxygen in ozone flames. It should be noted, however, that ozone reactions from the MSU mechanism [25,30] excluding excited oxygen species are mostly balanced, and their implementation in the recent studies of combustion enhancement by ozone [6,[35][36][37][38][39] is justified. Yet, conclusions based on the complete set of reactions taken from the MSU mechanism by Ombrello et al [7], and by Bourig et al [26], should be treated cautiously.…”
