Book excerpt: Recent difficulties with predicting ignition and flamespreading in gun simulators have been attributed to assumptions concerning the chemical heat release at low pressures used in the interior ballistic codes. This has generated interest in obtaining quantitative information on the chemical energy (E) released by propellant combustion at low pressures. An investigation was initiated to determine the feasibility of obtaining E from heat of explosion (HEX) experiments at low loading densities and varying levels of prepressurization. The degree of the correlation of HEX with flame characteristics (structure and burn rate) will be indicative of the value of these data for predicting gun performance. Heats of explosion were measured in a pressurized calorimeter bomb which contained a piezoelectric transducer. Calorimeter combustion products were analyzed by gas chromatography. Difficulties with ignition were encountered as initial pressures and loading densities were lowered. These difficulties exacerbated problems with reproducibility of HEX data and place lower limits on operating pressure in the calorimeters. Preliminary results indicate that if these difficulties can be overcome then measured HEX may be used to determine nonequilibrium values for E corresponding to partial heat release of propellants burning at low pressures. Such data may be useful for describing early pressurization transients in IB gun models. Keywords: Heat of explosion; Gun propellants; Propellant flames; Simulators. (KT).

Available in PDF, EPUB and Kindle. Book excerpt: When a system containing solid explosive is engulfed in a fire it receives a heat flux that causes the temperature of the system to rise monotonically. The temperature rise can often be approximated by a linear rise for extended periods of time. When some portion of the explosive, usually near the surface, reaches its ignition temperature it will begin to burn. If the explosive is unconfined, or can breach its confinement at low pressure, it will burn, not explode. Typically the burn front will propagate through a slab or shell at speeds on the order of a centimeter a minute. If the explosive is confined, the gas resulting from its burning will generate pressures high enough to rupture the confinement, but the peak pressure will generally be only a fraction of the pressure from a true detonation. When a system is not engulfed in the fire, but is close enough to be heated slowly by the fire, the behavior will be different. If the explosive is heated slowly it will have a nearly uniform temperature and ignition will occur inside the explosive. This almost always causes an explosion, even when the explosive as a whole is unconfined. The reason for this behavior is not well understood but slow heating of an explosive generally results in a more violent explosion than fast heating. These two situations are recognized by fast and slow cookoff tests used with munitions. Many munitions pass the fast cookoff test with heating rates around 2 K/min. Slow cookoff tests with heating rates around 4 K/hr generally result in an explosion. (The equations in this paper assume absolute temperatures in Kelvins, equal to Celsius + 273.16.) Mathematical models predicting the time to explosion are usually based on the assumption that the explosive has a uniform initial temperature and that the outer surface is suddenly raised to some temperature and held there. The earliest such models where those of Semenov and Frank-Kamenetskii.

This book was released on 1996-12-31 with total page 312 pages. Available in PDF, EPUB and Kindle. Book excerpt: The security and economic stability of many nations and multinational oil companies are highly dependent on the safe and uninterrupted operation of their oil, gas and chemical facilities. One of the most critical impacts that can occur to these operations are fires and explosions from accidental or political incidents. This publication is intended as a general engineering handbook and reference guideline for those personnel involved with fire and explosion protection aspects of critical hydrocarbon facilities. Design guidelines and specifications of major, small and independent oil companies as well as information from engineering firms and published industry references have been reviewed to assist in its preparation. Some of the latest published practices and research into fire and explosions have also been mentioned.

This book was released on 1994-03-18 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of explosives to generate ultrahigh pressures and thereby modify the structure and properties of condensed matter began in the 1950s and has since then become an important area of science. This book discusses the physical principles and experimental techniques of shock compression as applied to problems of inorganic chemistry and materials science. It begins with the fundamental physics of shock waves, the dynamic compressibility of solids, and physical and chemical transformations that may be produced by a shock. The second chapter turns to the experimental conditions for measurements and the preparation of ampoules. Subsequent chapters discuss: microstructural changes, such as fragmentation, shock hardening, and shock compaction; phase transformations in graphite, oxides, metals, and other materials; and chemical transformations, including mass transfer, decomposition, and diamond synthesis.
