Determinants of ignition times: Topographies of cell assemblies and the activation delays they imply
Behavioral and Brain Sciences, 2004Abstract The cell assembly model of language posits that words are laid down in the cortex by discrete sets of neurons distributed over specific parts of the brain. The strong internal links of these “word webs” may not only bind articulatory and acoustic knowledge of a lexical item, they may also link word and meaning; for example, by connecting ...

High temperature ignition delay times of C5 primary alcohols
Combustion and Flame, 2013Abstract Ignition delay times of the three C5 primary alcohol isomers (n-pentanol, iso-pentanol and 2-methyl-1-butanol) were measured behind reflected shock waves. Experiments were conducted in the temperature range of 1100–1500 K, pressures of 1.0 and 2.6 atm, equivalence ratios of 0.25, 0.5 and 1.0, and O2 concentration in the fuel/O2/Ar mixtures ...

Ignition Delay-Times of n-Pentane in a Shock Tube
1995The combustion kinetics of n-pentane was investigated in detail for the first time. Ignition delay times of n-C5H12 and Oxygen mixtures diluted in Argon were measured over a wide range of compositions, pressures and temperatures. The 240 experiments were statistically correlated to an overall equation $$\tau = {10^{ - 12.8}}\exp [ + 34610/RT ...

Shock tube measurements of branched alkane ignition delay times
Fuel, 2014Abstract Ignition delay times for three branched alkanes: 2,4-dimethylpentane, 2,5-dimethylhexane and iso-octane, were measured behind reflected shock waves. The ignition delay time measurements cover the temperature range of 1313–1554 K, with pressures near 1.5 and 3 atm, equivalence ratios of 0.5 and 1 in 4% oxygen/argon. Regression analyses of the

Combustion Reaction Mechanisms from Ignition Delay Times
1981Ignition studies behind reflected shock waves in a single pulse shock tube are described for three combustion systems: 1. C2N2+O2→CO+N2 2. COS+O2→CO+SO2 3.

Effect of Ignition Delay Time on Autoignited Laminar Lifted Flames
Transactions of the Korean Society of Mechanical Engineers B, 2011Autoignition characteristic is an important parameter for designing diesel or PCCI engines. In particular, diesel spray flames are lifted from the nozzle and the initial flame is formed by an autoignition phenomenon. The lifted nature of diesel spray flames influences soot formation, since air will be entrained into the spray core by the entrainment of

Study on the Ignition Delay Time of n-Heptane Fuels
Applied and Computational EngineeringAs a basic standard for gasoline anti-knock performance, the ignition delay time (IDT) of n-hexane is essential for optimizing internal combustion engine efficiency and lowering pollutants. IDT is an essential metric in combustion research because it represents the reactivity of fuels under different thermodynamic circumstances and offers critical ...
