“…The first is located at NUI Galway (NUIG). It is an updated version of the shock tube described in detail by Darcy et al [45]. It has an inner diameter of 6.35 cm, a driver section 3 m in length which is separated from the driven section (5.7 m in length) by a double diaphragm section (3 cm in length) which houses two pre-scored aluminium diaphragms per experiment.…”

“…The previous shock tube [20] was replaced so that we could perform higher pressure experiments with the operational pressure limit of the present shock tube being approximately 100 atm. Ignition delay times of n-butylbenzene/air mixtures at 50 atm were newly obtained and those at lower pressure were published previously [22].…”

“…Starting with the small alkylbenzenes, measurements and modeling studies have been performed for ignition delay times for toluene [4]- [12], ethylbenzene [9]- [14], xylenes [9][12] [14]- [17] and n-propylbenzene [9][10] [18]- [20] at various temperatures and pressures. In the case of n-butyl benzene, ignition characteristics as well as flame characteristics have been studied.…”

“…• The kinetic model of Darcy et al [18] found the reactions involving HO 2 to display a strong promoting effect on oxidation; especially, the reaction of benzyl + HO 2 → C 6 H 5 CH 2 O + OH. As Figure 6 demonstrates, the most accessible channel for R3 + HO 2 produces the benzyl radical.…”

“…Whilst the reaction RH + HO 2 → R + H 2 O 2 exhibits a central role in lowtemperature oxidation mechanisms of alkyl benzenes, the addition of HO 2 to phenylalkyl radicals holds comparable prominence. The work of Metcalfe et al [17] on oxidation of toluene and Darcy et al on oxidation of nPB [18] demonstrated that, addition of HO 2 to benzyl radical represents the most important reactivity-promoting reaction. Kinetic data for this reaction were extracted from oxidation models on alkanes.…”
