Explosion - Wikipedia
An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when ...

A Common Explosion Mechanism for Type Ia Supernovae | Science …
2007年2月9日 · Type Ia supernovae, the thermonuclear explosions of white dwarf stars composed of carbon and oxygen, were instrumental as distance indicators in establishing the acceleration of the universe's expansion. However, the physics of the explosion are debated.
Explosion Physics - SpringerLink
At present, the majority of studies opine that impact induces explosion through one of the four mechanisms below to convert mechanical energy into heat, creating localized hot spot in explosive for initiation: (1) Hot spot generated in local shear band created by impact initiates explosion; (2) hot spot generated in adiabatic compressed gas ...
explosion occurs because the cooler liquid expands as it is converted to vapor, creating high pressures. These are called physical explosions. A common example is a steam explosion, which occurs when liquid water is accidentally introduced into …

6 天之前 · Explosion mechanisms of IPN mist are obtained. This study establishes a numerical model for dust flow and dust cloud explosion, elucidating the mechanisms underlying HMX dust cloud explosions and the variations in explosion parameters concerning concentration and …
Combustion - Explosions, Chemical Reactions, Heat | Britannica
2024年11月15日 · The transition from combustion to explosion is caused by an acceleration of the reaction, induced either by a rise in temperature or by increasing lengths of the reaction chain. The first is called thermal explosion, and the second is called chain explosion.
The Explosion Phenomenon - The Mechanisms of Explosions
2023年4月14日 · Each explosive system is characterized by the energy E lib, which is released during the explosion. The higher the E lib value, the greater the intensity of the explosion effects. An Explosive Atmosphere (ATEX) is the mixture with air, in some proportions, of a “combustible” or “flammable” product, which may be: a gas; a vapor emitted ...
Supernova explosions in the Universe - Nature
2000年2月17日 · Supernovae and γ-ray bursts share the distinction of being the most powerful explosions in the cosmos, and recent observational and theoretical breakthroughs and a renewed appreciation of the...
The Chemistry of Explosions - Department of Chemistry
Explosives are substances that undergo a rapid oxidation reaction with the production of large quantities of gases. It is the sudden buildup of gas pressure (see products above) that constitutes the nature of an explosion. The speed at which explosives decompose permits their classification as high or low explosives.
