Vented gas explosions
… protection measures against gas and dust explosions.The key problem in venting is the appropriate design of the vent area necessary for an effective release of the material i.e. the pressure developed during explosion did not cause any damage to the plant protected.Current gas explosion …

Nonlinear effects near an explosions
The purpose of this study is to find the dimensions of the shattered zone produced by the explosion of a spherical charge, in terms of the properties of the medium and the weight of the explosive charge; and then, to establish a relationship between the size of this nonlinear region and the …

Homogeneous and stratified vented gas explosions
… phenomena between stratified and homogeneous explosions and between partially filled and fully filled geometries to the conclusion that the explosion severity recorded in stratified mixtures towards the lean flammability limit was in many cases much higher than the fuel concentration would …

The Spontaneous Triggering of Small-Scale Vapour Explosions
… work on the spontaneous triggering of vapour explosions, a phenomenon which can sometimes occur when two liquids at very different temperatures are brought into contact. The energy for the explosion is derived from the thermal energy in the hot liquid which is transferred very rapidly to the …

Experimental investigation of constant volume sulfur dust explosions
… pressure-time data to measure ame speed in dust explosions. These results were applied to measurements of the fundamental combustion quantities, such as ame temperature and speed, to ascertain the burning regime of sulfur dust ames. A two-dimensional laser extinction technique was used to …

Impulse loading of near-field shallow-buried explosions
Prediction of the total impulse for a mine-protected vehicle must be empirically determined for South African Paardefontein soil pit soil at the start-up phase of a new vehicle project, particularly when experimental data are not yet available for the calibration of computational efforts. The total …

Investigation into the electromagnetic field generated by explosions
This project was undertaken to identify any discernible field or wave in the low frequency EM spectrum, focusing particularly on the magnetic field. The work published by Soloviev in 2002 and Adushkin in 2004 served as guidelines on test procedure and setup. Testing of this nature was not found in …

Experimental investigations on gas explosions in partially confined regions
The primary objectives of the described research were to examine the underlying physical phenomena occurring during flame/obstacles interactions in various chambers of low L/D ratio and to develop a new empirical equation for explosion venting. A literature review suggested that the propagating …

The Blast Waves From Unconfined Axisymmetric Vapour-Cloud Explosions
This dissertation presents a systematic study of the blast waves produced by axisymmetric detonation waves and constant velocity as well as accelerating deflagration waves propagating through homogeneous axisymmetric clouds whose energy density approximate that of a typical hydrocarbon-air mixture. …

Protection of electronics in submerged enclosures against underwater explosions
In the milieu of military sea mine design, it is often necessary to design mines that are to be placed at small distances from each other. A possible tactical purpose may require that each mine be set to explode at controlled instances in time without disturbing the operation of the other mines in …

Response of plates subjected to air-blast and buried explosions
Explosive threats have become more prevalent in both military and terrorist theatres of conflict, showing up largely in the form of Improvised Explosive Devices (IED) which are often buried in soil to conceal them and increase their effectiveness. The response of a structure subjected to a blast …

Explosions and unbounded growth in nonlinear delay differential equations: Numerical and asymptotic analysis
This thesis investigates the asymptotic behaviour of a scalar, nonlinear dierential equation with a fixed delay, and examines whether the properties of this equation can be replicated by an appropriate discretisation. We begin by considering equations for which the solution explodes in finite time. …

Experimental study of the interaction between aluminum and hydrogen fluoride in biocidal explosions
… higher quality measurements. The simplified explosions used gas phase halogen fuel (1,1-difluoroethane) diffused into a propane/air explosion with pneumatically injected powdered particulates. The results showed that neither the presence of aluminum, nor alumina, suppressed the HF population …

The effects of underwater explosions on fish with techniques to mitigate those effects
"This dissertation is divided into two broad areas of study. The first section focuses on the ""state-of-the-science"" of environmental effects of underwater explosive use. The literature review demonstrated a lack of standardization of methodologies. A number of methodological questions were …
