Blast wave - Wikipedia
In fluid dynamics, a blast wave is the increased pressure and flow resulting from the deposition of a large amount of energy in a small, very localised volume. The flow field can be approximated as a lead shock wave , followed by a similar subsonic flow field.
The Blast Wave - Atomic Archive
The Blast Wave. A fraction of a second after a nuclear explosion, the heat from the fireball causes a high-pressure wave to develop and move outward producing the blast effect. The front of the blast wave, i.e., the shock front, travels rapidly away from the fireball, a moving wall of highly compressed air.

Blast Wave - an overview | ScienceDirect Topics
However, in nuclear power plants, the expansion of blast wave happens in an enclosed space. The blast wave can diffract through a narrow opening and refract as they pass through materials. When a blast wave reaches the boundary between two different materials, it can be transmitted, absorbed and reflected.
Blast Waves - SpringerLink
This book examines blast waves—their methods of generation, their propagation in several dimensions through the real atmosphere and layered gases, and their interactions with simple structures—thereby providing a broad overview of the field.
Knowledge of the arrival time of a blast wave at various distances from the source enables a radius time relationship to be developed, from which other key parameters such as
Blast wave kinematics: theory, experiments, and applications
2021年10月18日 · Abstract: Measurements of the time of arrival of shock waves from explosions can serve as powerful markers of the evolution of the shock front for determining crucial parameters driving the blast. Using standard theoretical tools and a simple ansatz for solving the hydrodynamics equations, a general expression for the Mach number of the shock ...
