Definition
Noun: A blast wave is a region of extremely high pressure and energy that moves outward very rapidly from the center of an explosion, traveling through a medium like air or water. It is a type of shock wave characterized by a sudden, violent change in pressure.
Usage
The term blast wave is used to describe the destructive, expanding front of pressure produced by a powerful explosion. * The blast wave from the detonation shattered windows over a mile away. * Researchers study the effects of a blast wave on building structures. * The initial blast wave is followed by a period of negative pressure.
Advanced Usage
- Blast wave propagation: Refers to how the blast wave travels and dissipates through an environment.
- The model simulates blast wave propagation through an urban canyon.
- Blast wave front: The leading edge of the high-pressure region.
- The blast wave front can be visualized using high-speed photography.
Variants and Related Words
- Shock wave (noun): A more general term for a powerful pressure wave. All blast waves are shock waves, but not all shock waves (e.g., from supersonic aircraft) are blast waves.
- Overpressure (noun): The pressure, caused by a blast wave, exceeding normal atmospheric pressure. It is a key measure of a blast wave's destructive potential.
Synonyms
- Shock wave
- Pressure wave
- Explosion wave
Related Phrases
- Blast wave effects: The physical consequences, such as impact on structures, organs, or the environment.
- The study focused on the blast wave effects on lung tissue.
- Blast wave mitigation: Efforts to reduce the impact or strength of a blast wave.
- The wall's design is intended for blast wave mitigation.
Noun
- a region of high pressure travelling through a gas at a high velocity
- the explosion created a shock wave
