Experimental and modeling study of the autoignition of cyclopentene [PDF]
International Journal of Chemical Kinetics, 2007 AbstractIgnition delay times of cyclopentene–oxygen–argon mixtures were measured behind reflected shock waves. Mixtures contained 0.5% or 1% of hydrocarbons for equivalence ratios ranging from 0.5 to 1.5. Reflected shock wave conditions were as follows: temperatures from 1300 to 1700 K and pressures from 7 to 9 atm.

Neki aspekti primene različitih metoda u ispitivanju eksplozivnih materija / Some aspects of applying different methods in testing explosives [PDF]
Vojnotehnički Glasnik, 2004 Eksplozivne materije, pored relativno velike osetljivosti na dejstvo spoljnih impulsa, imaju sklonost ka termičkoj dekompoziciji usled čega postoji opasnost od njihovog samozapaljenja u slučaju ispunjenja kritičnih uslova. Radi toga uspostavljen je čitav

Hydrogen SI and HCCI Combustion in a Direct-Injection Optical Engine [PDF]
, 2009 Hydrogen has been largely proposed as a possible alternative fuel for internal combustion engines. Its wide flammability range allows higher engine efficiency with leaner operation than conventional fuels, for both reduced toxic emissions and no CO2 ...

Autoignition flame dynamics in sequential combustors [PDF]
Combustion and Flame, 2018 Abstract This numerical study investigates the linear and non-linear flame dynamics in the second stage of a sequential combustor, with methane fuel injection into vitiated hot gas. It focuses on the heat release rate response of the sequential flame to entropy waves.
