Word Finder - detonation

definition

An explosion or sudden report made by the near-instantaneous decomposition or combustion of unstable substances. Specifically, combustion that spreads supersonically via shock compression.

example

the detonation of gun cotton

definition

Engine knocking, an improper combustion in internal combustion engines

In order for detonation to occur, a sphere of plutonium has to be rapidly compressed by a series of conventional high explosives.

These results showed clearly that liquefied acetylene was far too dangerous for general introduction for domestic purposes, since, although the occasions would be rare in which the requisite temperature to bring about detonation would be reached, still, if this point were attained, the results would be of a most disastrous character.

If this is not true can somebody explain how the detonation of a small amount of TNT can produce megatons of explosive force?

Skimming the head also increases the compression ratio and to avoid detonation with low octane fuel a low compression piston is used.

Detonation is generally caused by excessive heat, excessive cylinder pressure, improper ignition timing, inadequate fuel octane or a combination of these.

However much compressed by mechanical means it is still a porous mass, and when it is confined as in a gun the flame and hot gases from the portion first ignited permeate the remainder, generally causing it actually to detonate, or to burn so rapidly that its action approaches detonation.

The pulse detonation wave engine offers a marked increase in efficiency and a simplification of design over current rocket and ramjet engines.

O Octane Number A measure of a fuel 's ability to prevent detonation in a spark ignition engine.

The detonation of this particular storyline hit all the right notes in the episodes dealing with it and the ripple effects were felt for months.

A charge of compressed wet guncotton may be exploded, even under water, by the detonation of a small primer of the dry and waterproofed material, which in turn can be started by a small fulminate detonator.

The explosive wave from the dry guncotton primer is in fact better responded to by the wet compressed material than the dry, and its detonation is somewhat sharper than that of the dry.

The first attempts to utilize the explosive power of nitroglycerin were made by Nobel in 1863; they were only partially successful until the plan, first applied by General Pictot in 1854, of developing the force of gunpowder in the most rapid manner and to the maximum extent, through initiative detonation, was applied by Nobel to nitroglycerin.

Continuing these experiments, they found that in acetylene gas under ordinary pressures the decomposition brought about in one portion of the gas, either by heat or the firing in it of a small detonator, did not spread far beyond the point at which the decomposition started, while if the acetylene was compressed to a pressure of more than 30 lb on the square inch, the decomposition travelled throughout the mass and became in reality detonation.

Such endothermic bodies are nearly always found to show considerable violence in their decomposition, as the heat of formation stored up within them is then liberated as sensible heat, and it is undoubtedly this property of acetylene gas which leads to its easy detonation by either heat or a shock from an explosion of fulminating mercury when in contact with it under pressure.

Initially starting on guitar at 9 then pursued percussive detonation (drums).
