“…Different sorts of nanostructures were considered as additives. Among them were Al oxidized [12][13][14][15][16] and nonoxidized [13,14,17] nanoparticles, boron [18,19], carbon [20][21][22], iron [18] and CeO 2 [23] nano-sized particles. Both experimental and theoretical studies proved that addition of nanoparticles to hydrocarbon fuels can enhance the ignition and combustion [11,12,14,[17][18][19][20][21][22].…”

Both lower and higher heating values of small Al n C m clusters (n=0...5, m=0...5) were estimated via thermochemical analysis based on quantum chemical calculations. Combustion enthalpies, the final temperature and the potential work that can be released during expansion of combustion products were calculated for such clusters assuming the chemical equilibrium in the combustion exhaust. The analysis of the potentialities of small Al n C m clusters as energetic materials was conducted. It was shown that the AlC 4 and AlC 5 clusters are very promising additives for highly energetic fuels. Combustion of these clusters in oxygen can provide very high temperature (∼5400 K for stoichiometric conditions). Moreover, such clusters can serve as unicomponent fuel. It was revealed that small clusters possess higher heating value than that for corresponding bulk material.

Influence of Particle on Gas Detonation by Shock

There exist evidence, that the gaseous detonation passing through a cloud of solid particles could be attenuated or even suppressed. Contrary to these known works, in the present article, we have found that just one single 160-micron particle can serve as a trigger for the detonation onset. By numerical simulation, we have obtained that there are the concentration ratio limits, in which single particle is enough to initiate gaseous detonation, although without particle the detonation is not ignited in the same conditions in a tube of restricted size. In other words, the presence of a solid particle in the combustible mixture could decrease significantly the ignition delay time. Using of temperature pattern visualization, we have demonstrated that the ignition arises in the subsonic region located between the particle and the bow shock front. The approximations of the used model are discussed. It is shown that used assumptions are valid within investigated time intervals.
