explosion, detonation, blowup(noun)
a violent release of energy caused by a chemical or nuclear reaction
the act of detonating an explosive
An explosion or sudden report made by the near-instantaneous decomposition or combustion of unstable substances as, the detonation of gun cotton. Specifically, combustion that spreads supersonically via shock compression.
Engine knocking, an improper combustion in internal combustion engines
Origin: From détonation.
an explosion or sudden report made by the instantaneous decomposition or combustion of unstable substances' as, the detonation of gun cotton
Origin: [Cf. F. dtonation.]
Detonation involves a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations are observed in both conventional solid and liquid explosives, as well as in reactive gases. The velocity of detonations in solid and liquid explosives is much higher than that in gaseous ones, which allows the wave system to be observed with greater detail. Gaseous detonations normally occur in confined systems but are occasionally observed in large vapor clouds. They are often associated with a gaseous mixture of fuel and oxidant of a composition, somewhat below conventional flammability limits. There is an extraordinary variety of fuels that may be present as gases, as droplet fogs and as dust suspensions. Other materials, such as acetylene, ozone and hydrogen peroxide are detonable in the absence of oxygen, a more complete list is given by both Stull and Bretherick. Oxidants include halogens, ozone, hydrogen peroxide and oxides of nitrogen. In terms of external damage, it is important to distinguish between detonations and deflagrations where the exothermic wave is subsonic and maximum pressures are at most a quarter of those generated by the former. Processes involved in the transition between deflagration and detonation are covered thoroughly for gasses by Nettleton.
Military Dictionary and Gazetteer
The instantaneous conversion of an explosive into gas; a term applied to the phenomena attending the explosion of certain substances, such as nitro-glycerine, chloride of nitrogen, iodide of nitrogen, gun-cotton, the picrates, etc. Detonation, or explosion of the first order, is distinguished from ordinary explosion, or explosion of the second order, by the different way in which the explosion is propagated. Ordinary explosion proceeds by inflammation, being nothing more than a rapid combustion. Detonation is propagated by vibration. A detonating agent is a substance used to produce the initial vibration, or “impulse of explosion.” The exploder, or cap, used for this purpose is usually primed with fulminate of mercury, a substance having a wide range in bringing about detonation in the high explosives.
