Default Re: What exactly is Detonation

Detonation is a process of combustion in which a supersonic shock wave is propagated through a fluid due to an energy release in a reaction zone. It is the more powerful of the two general classes of combustion, the other one being deflagration. In a detonation, the shock compresses the material thus increasing the temperature to the point of ignition. The ignited material burns behind the shock and releases energy that supports the shock propagation. This self-sustained detonation wave is different from a deflagration, which propagates at a subsonic rate (i.e., slower than the sound speed in the material itself). Because detonations generate high pressures, they are usually much more destructive than deflagrations.

Detonations can be produced by explosives, reactive gaseous mixtures, certain dusts and aerosols.
