When flame velocities are low, the effect of a deflagration is to release heat, such as in a flash fire. At flame velocities near the speed of sound, the energy released is in the form of pressure, and the …

Mar 27, 2023 · 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 …

Jun 27, 2023 · Deflagration is a combustion process characterized by the subsonic propagation of a flame front through a combustible material. Unlike detonation, which involves a rapid and supersonic …

The meaning of DEFLAGRATION is the process of deflagrating; specifically : a chemical reaction producing vigorous evolution of heat and sparks or flame and moving through the material (as black …

Nov 7, 2025 · Deflagration is a rapid combustion where a flame propagates through a fuel and oxidizer mixture at a speed lower than the speed of sound in that medium. This process is characterized by a …

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.

Deflagration is an explosion in which the speed of burning is lower than the speed of sound in the surroundings. A detonation generates greater pressures and is more destructive than a deflagration. …

Sep 11, 2025 · The moment a reaction stops being ‘burning’ and becomes a ‘deflagration’ is the instant an atmospheric shock wave first appears. Deflagration to Detonation: This transition was already well …

Jan 22, 2023 · Deflagration is a surface phenomenon, with the reaction products flowing away from the unreacted material along the surface at subsonic velocity. Confinement of the reaction increases …

May 21, 2024 · 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 …
