An analysis of the explosion limits of hydrogen-oxygen mixtures
The Journal of Chemical Physics, 2013In this study, the essential factors governing the Z-shaped explosion limits of hydrogen-oxygen mixtures are studied using eigenvalue analysis. In particular, it is demonstrated that the wall destruction of H and HO2 is essential for the occurrence of the first and third limits, while that of O, OH, and H2O2 play secondary, quantitative roles for such ...

The effect of stirring on the limits of thermal explosion
Combustion Theory and Modelling, 1997It is analysed theoretically how the stirring of an exothermically reacting fluid layer affects its thermal explosion limits. Analytical and numerical analyses reveal that, in accordance with the intuitive expectations, the short-scale stirring makes the thermal explosion more difficult through the increased heat transfer to the boundaries.

Upper Limit in Explosive Chain Reactions
Nature, 1933THE existence of an upper limiting pressure for explosion in thermal chain reactions has been explained in two ways. (1) The rate of branching of the chains, at the limit, is just sufficient to balance the rate of gas phase deactivation of the carriers ; (2) a sudden change in the nature of the absorbed layer of gas on the walls of the reaction tube ...

Detonation limits in composite explosives
Symposium (International) on Combustion, 1965Characteristic differences in the effect of density distinguish composite explosives (based on ammonium nitrate or ammonium perchlorate as oxidizer with an organic fuel) from molecular explosives like TNT or pure ammonium perchlorate. The behavior suggests that the reaction slows down when density is increased in composite explosives, while in ...

On limiting distributions in explosive autoregressive processes
Statistics & Probability Letters, 1998Let \[ Y_n= \beta'\widetilde{Y}_{n-1}+ \varepsilon_n, \quad\varepsilon_n\text{ i.i.d. } N(0,1), \quad n=1,2,\dots \] be the \(p\) th order purely explosive autoregressive process where \(\beta= (\beta_1,\dots, \beta_p)'\) is a real \(p\)-vector, which is unknown and \(\widetilde{Y}_j= (Y_j,\dots, Y_{j-p+1})'\).

A criterion for the isothermal first explosion limit
Combustion and Flame, 1982Abstract The term “explosion” has been used for a wide variety of phenomena from essentially no reaction to complete fuel use. Previous criteria for prediction of explosions have correspondingly not considered extent of fuel consumption. A simple zeroth-order outer singular perturbation scheme is used here on the equations modeling isothermal ...
