Deflagration (Lat: de + flagrare, 'to burn down') is subsonic combustion in which a pre-mixed flame propagates through an explosive or a mixture of fuel and oxidizer. [1] [2] Deflagrations in high and low explosives or fuel–oxidizer mixtures may transition to a detonation depending upon confinement and other factors.

2023年6月27日 · The main difference between detonation and deflagration is that deflagration is a subsonic combustion process in which the flame front propagates through a combustible material at a speed lower than the speed of sound.

2023年3月27日 · A deflagration is an explosion where the flame speed is lower than the speed of sound, which is approximately equal to 335 m/sec (750 mph). Explosives that deflagrate are known as low explosives. The actual speed of the explosion can …

2024年5月21日 · A deflagration is a very fast moving and hot fire that moves as heated materials ignite cold ones. This distinguishes it from combustion, a slower rate of spreading, and detonation, an even faster-moving fire that can also create a shock wave and cause additional damage.

The meaning of DEFLAGRATE is to cause to deflagrate. Did you know?

Deflagration to detonation transition (DDT) refers to a phenomenon in ignitable mixtures of a flammable gas and air (or oxygen) when a sudden transition takes place from a deflagration type of combustion to a detonation type of explosion.

Deflagration is the most common mode of flame propagation and is characterised by a smoother blast wave that propagates at subsonic velocity relative to the unburned gas immediately ahead of the flame.

There is a unique solution for the (weak) deflagration, giving a definite wave speed for each gas mixture Weak deflagrations (flames) travel typically at 10 - 100 cm/s and p ∞ /p 0 ~ 1, T ∞ /T 0 ~ 6, ρ ∞ /ρ 0 ~ 1/6 15 Detonations: Compression waves that propagate supersonically (1 < M 0 < ∞)

Deflagration occurs at a subsonic speed, with a controlled and gradual release of energy, while detonation propagates at supersonic speeds, resulting in an explosive release of energy. The pressure, flame structure, and applications associated with each process also differ significantly.

As nouns the difference between conflagration and deflagration is that conflagration is a large fire extending to many objects, or over a large space; a general burning while deflagration is...
