Simulation and Measurements of Small Arms Blast Wave Overpressure in the Process of Designing a Silencer

Measurement Science Review, 2015
Simulation and measurements of muzzle blast overpressure and its physical manifestations are studied in this paper. The use of a silencer can have a great influence on the overpressure intensity.

Experimental Investigation of the Influence of Opening Dynamics on the Blast Overpressure Anisotropy in BLEVEs

Chemical Engineering Transactions
The Boiling Liquid Expanding Vapor Explosion (BLEVE) is one of the most dangerous industrial accidents, occurring when a pressure vessel containing a pressure liquefied gas like LPG or heated water suffers a catastrophic structural failure.

Evaluating Blast Wave Overpressure From Non-spherical Charges Using Time Of Arrival From High-speed Video [PDF]

, 2023
Scaled distance is used to predict blast wave overpressure surrounding the detonation of a known mass of explosive under the assumption that the charge geometry is spherical.

Effects of Entrance Shape and Blast Pocket on Internal Overpressure Mitigation for Protective Tunnels Exposed to External Detonation on the Ground

Applied Sciences, 2023
This study presents a numerical analysis to reduce the overpressure inside protective tunnels for external detonations. A three-dimensional computational fluid dynamics model of a tunnel subjected to detonation for a hemispherical charge with a charge ...

A Wireless Transient Attenuated-exponential Overpressure Beamforming with for Far-field Blast Source Localization [PDF]

, 2022
Time-domain beamforming is more suitable for blast wave transient signal than frequency-domain beamformer because wide-band spectrum of noise makes the beamforming image less clear.

Predictive model of back-wall overpressure behind a cantilever wall

AIP Advances, 2023
To reduce the hazards posed by blast shock waves, important potential targets are usually shielded by cantilever walls. The main factor that indicates whether there is damage is the back-wall overpressure, and of concern here is predicting the back-wall ...

Rapid release of tissue enzymes into blood after blast exposure: potential use as biological dosimeters. [PDF]

PLoS ONE, 2012
Explosive blast results in multiple organ injury and polytrauma, the intensity of which varies with the nature of the exposure, orientation, environment and individual resilience.

Experimental study on the characteristics of overpressure wave to ventilation facilities during gas explosion and automatic shock relief devices

Geomatics, Natural Hazards & Risk, 2020
Ventilation facilities could easily be destroyed by gas explosion in a coal mine and usually lead to the cascade collapse of the entire ventilation system.
