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

DNS Investigation on Autoignition and Flame Propagation in HCCI Combustion
Journal of Fluid Science and Technology, 2011 2-dimensional direct numerical simulation (DNS) of autoignition and flame propagation of turbulent premixed mixture has been conducted to investigate the turbulent combustion mechanism in homogeneous charge compression ignition (HCCI) engines.

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.

An elementary model for autoignition of laminar jets [PDF]
Proceedings of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 In this paper, we formulate and analyse an elementary model for autoignition of cylindrical laminar jets of fuel injected into an oxidizing ambient at rest. This study is motivated by renewed interest in analysis of hydrothermal flames for which such configuration is common.

Autoignitions and detonations in engines and ducts [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2012 The origins of autoignition at hot spots are analysed and the pressure pulses that arise from them are related to knock in gasoline engines and to developing detonations in ducts. In controlled autoignition engines, autoignition is benign with little knock.

Influence of fuel properties on knock under lean combustion conditions
Nihon Kikai Gakkai ronbunshu, 2021 Internal combustion engines today are required to provide even higher levels of thermal efficiency. Raising the compression ratio and applying lean combustion are effective measures for increasing the thermal efficiency of internal combustion engines ...
