2.2. Explosion
The term “explosion” is used to describe a rapid release of energy. The energy released in an explosion is normal from chemical energy, fluid expansion energy, or vessel strain energy. Damage caused by explosions varies according to different energy dissipation mechanisms, such as a pressure wave, projectiles, thermal radiation, and acoustic energy. Taking overpressure as an example, 5–7 psig (pounds per square inch gauge) will nearly cause complete destruction of houses (Clancey, 1972).
This section first briefly introduces basic concept about explosion, for example, classification and characterization of explosion, deflagration, and detonation. Then it demonstrates some models for explosions caused by different energy types, ...
