Autoignition of hydrogen at high pressure

An evaluation of detailed reaction mechanisms for hydrogen combustion under gas turbine conditions

“…They yielded good agreement of predicted and measured burning velocities at different equivalence ratios at atmospheric pressure. Cain [24] used a mechanism of Jachimovski and Mclain [25] containing 17 reversible reactions for the simulation of auto-ignition of hydrogen at pressures between 3.5 and 7 MPa. Miller and Bowman [26] developed a detailed mechanism for nitrogen chemistry including 20 reversible reactions for H 2 /O 2 kinetics.…”

Detonation waves induced by a confined wedge

“…4 also shows two boundaries, a and b. The first is the locus for the combination of Mach number and wedge angle that yields the ignition temperature of 1100 K [5] while the second is the locus of the CJ pressure (p CJ = 0.665 MPa for a stoichiometric hydrogen/air mixture) behind the bow shock. Both of these boundaries are obtained assuming an inert flow with a constant specific ratio of 1.4.…”

Kinetic model of alkane oxidation at high pressure from methane ton-heptane

“…Cain [1] studied experimentally and theoretically hydrogen autoignition at high pressure (35-70 atm) and at a temperature of 1150 K. The results of the kinetic analysis show that at the given temperatures and pressures hydrogen ignition is initiated by OH radicals formed 428 V.P. Zhukov in the reaction:…”
