This paper reports on the ignition and flame propagation characteristics of aluminum/ copper oxide (Al/CuO) nanothermite at different packing density, manufactured from 40 nm commercial Al CuO nanopowders. A 3.5W continuous wave laser was used to ignite samples in argon atmospheric pressure, a high speed camera captured propagation. The images revealed that fast heating creates significant material ablation, followed by heat transfer along heated surface. bulk occurs near edge top surface,...
A detailed kinetic model devoted to the gas phase hypergolic ignition of MMH/NTO mixtures below 298 K and their combustion above 1000 is presented in this study. It consists 403 equilibrated reactions among 82 species. This mechanism has been confronted with theoretical data available literature. The agreement between theory predictions found be good. Important for at low initial temperature pressure have identified through sensitivity analyses. Two competing pathways can explain...
Shock tube ignition delay times have been measured for 3-pentanone at a reflected shock pressure of 1 atm (±2%), in the temperature range 1250-1850 K, equivalence ratios 0.5-2.0 O(2) mixtures argon with fuel concentrations varying from 0.875 to 1.3125%. Laminar flame speeds also an initial over ratio range. Complementary previous studies [Pichon S., Black, G., Chaumeix, N., Yahyaoui, M., Simmie, J. Curran, H. J., Donohue, R. Combust. Flame, 2009, 156, 494-504; Serinyel, Z.; G.; J.; M....
Benzene and toluene were pyrolyzed under highly argon-diluted conditions at a nominal pressure of 20 bar in single-pulse shock tube coupled to gas chromatography/gas chromatography–mass spectrometry (GC/GC–MS) diagnostics. Concentration evolutions polycyclic aromatic hydrocarbon (PAH) intermediates measured temperature range 1100–1800 K by analyzing the post-shock mixtures. Different PAH speciation behaviors, regarding types, concentrations formation windows, observed two reaction systems. A...
A combined experimental and kinetic modeling study is carried out to explore the influences of added acetylene, ethylene, propylene, propyne on reaction schemes benzene pyrolysis. Pyrolysis with without presence C2- or C3- unsaturated hydrocarbons (HCs) conducted in a single pulse shock tube coupled gas chromatography-mass spectrometry technique. minimum 30 species detected each system, their mole fraction profiles are obtained over temperature range 1030–1800 K at nominal pressure 20 bar...
