Effect of Al/O Ratio on the Detonation Performance and Underwater Explosion of HMX‐based Aluminized Explosives

Propellants, Explosives, Pyrotechnics, 2013
AbstractThe performance of detonation and underwater explosion (UNDEX) of a six‐formula HMX‐based aluminized explosive was examined by detonation and UNDEX experiments. The detonation pressures, detonation velocities, and detonation heat of HMX‐based aluminized explosive were measured.

Considering the Influence of Chemical Reactions between Detonation Products on Specific Heat Ratio Calculating of the TNT Explosive with Small Explosive Charge Volume Ratio

Applied Mechanics and Materials, 2012
The formula and calculating method of specific heat ratio in confined explosion with small explosive charge volume ratios under considering chemical reactions of the detonation products was researched. Taking the TNT explosive as an example, a numerical calculating program was written, and the specific heat ratio of the confined explosion either ...

Isolation of components of plastic explosives for isotope ratio mass spectrometry

Forensic Chemistry, 2016
Abstract An improved method for the separation of the components of plastic explosives is described with the goal of stable isotope ratio analysis of each isolated component. The binder and plasticizer of a plastic explosive were extracted into cyclohexane, leaving the explosive components and other insoluble material.

On the Calculation of Steam Explosion Conversion Ratios from Experimental Data

Nuclear Science and Engineering, 1990
Conversion ratios reported for the Sandia National Laboratories intermediate-scale (FITS-B series) steam explosion experiments have been examined and recalculated. It is shown that these conversion ratios corresponding to the work done to compress the chamber air, {eta}{sub D} range from 0.05 to 1.04% compared with reported values of 0.2 to 8.6%.

Discrimination of earthquakes and explosions by the rayleigh-wave spectral ratio

Bulletin of the Seismological Society of America, 1970
Abstract Limited data from a long-period vertical seismometer and the prototype of a new mercury tiltmeter at the station, Harvard, Massachusetts, tend to confirm that the Rayleigh-wave spectral ratio of short- to long-period energy provides a useful discriminant for underground explosions in the Western United States at distances of ...

Enhanced signal-to-noise ratio and bandwidth through explosives design

Geophysics of the 21st Century - The Leap into the Future, 2003
Summary The signal-to-noise ratio and bandwidth of explosivesourced seismic data are the direct result of the properties of the explosives used and the nearsurface conditions. Conventional wisdom has dictated that certain properties are desirable in seismic explosives.

Spectral ratio analyses of explosion earthquakes at Sakurajima Volcano, Japan

Journal of Volcanology and Geothermal Research, 2019
Abstract It's quite important to clarify what physical parameters control the magnitude of volcanic explosion to understand magma processes in the conduit. Analyses of explosion earthquakes, which are associated with vulcanian eruptions, enable us to quantitatively evaluate dynamic process of the explosive eruptions.

Effect of blockage ratios on the characteristics of methane/air explosion suppressed by BC powder

Journal of Hazardous Materials, 2018
To investigate the effect of blockage ratios on the explosion suppression by powder suppressant, an experimental study was performed to suppress the methane-air explosion in a 5L duct with different blockage ratios and various concentrations of BC dry powder.
