Book Synopsis Small Scaled Reactive Materials Combustion Test Facility by : David P. Chonowski

Available in PDF, EPUB and Kindle. Book excerpt: Combustion of reactive materials forms an active area of research for reactive fragment and structural materials applications. Currently, reactive fragment tests involve high velocity (1-2 km/s), large caliber projectiles directed into blast chambers where overpressure is measured to quantify output. Unfortunately, these existing facilities suffer many issues including high cost per test, which limits the ability to perform true parametric studies, as well as limited access in some cases for diagnostics other than transient pressure. To address these issues, we developed a small-scale reactive materials combustion test facility based on the Remington .17 caliber rifle which safely launches projectiles at velocities approaching 1.3 km/s. By making custom projectiles and firing these into a small chamber with complete optical access, we are able to obtain transient pressure and capture high-speed imagery. The setup also allows for optical measurements including pyrometry and spectroscopy. In this work the diagnostic measurements are primarily the bullet velocity and chamber overpressure. After completion of the design and installation of the laser optical chronograph and the appropriate pressure transducers, several tests at velocities of 1.2 km/s were performed comparing inert bullets with those comprised of reactive metals in air, 100% nitrogen, and 40% oxygen rich environments. Therefore this paper outlines the major components of the combustion test facility, the system diagnostics and the effect that different intermetallics in various environments have on combustion performance. Results indicate that the facility performed as intended by capturing quantitative differences in the chemical energy release of various energetic systems. Further, through the post-processing of specimen residue with X-ray diffraction, the identification of reaction products provided better insight into the chemical reactions contributing to the observed energy release assisting in the determination of elements responsible for combustion performance.

Book Synopsis Chemical Reactivity Test for Thermal Stability by :
Download or read book Chemical Reactivity Test for Thermal Stability written by and published by . This book was released on 1994 with total page 10 pages. Available in PDF, EPUB and Kindle. Book excerpt: Lawrence Livermore National Laboratory (LLNL) has developed a thermal stability test procedure that is currently being evaluated by the Department of Defense (DOD) Explosives Safety Board as an equivalent alternate test to the DOD Technical Bulletin 700-2 "Thermal Stability Test at 75 degrees Celsius." This procedure will also be submitted for evaluation for acceptance under the similar test specified in the United Nations Recommendations on the Transport of Dangerous Goods, Tests and Criteria Manual. The LLNL Chemical Reactivity Test (CRT) is significantly more severe than the existing "Thermal Stability Test at 75 C" and is also quantitative in nature. It has been approved by the Department of Energy (DOE) Explosives Safety Committee as an equivalent alternate thermal stability test and has been in use by LLNL for over 30 years. It is currently used by other DOE and DOD organizations as the standard small-scale safety test for determining thermal stability and material compatibility. The LLNL CRT is run on a 0.250 gram sample for 22 hours at 120 degrees Celsius rather than the 50 gram sample for 48 hours at 75 C as required for the Thermal Stability Test. Thus the CRT is a much more severe test since it is run at 120 C rather than 75 C. Simple Arrhenius kinetics predict a material decomposition rate of approximately 25 times greater at 120 C than at 75 C. Any material under test that exhibits gas evolution exceeding 4 cubic centimeters/gram (approximately 0.8 % decomposition) is considered suspect and additional testing and/or evaluation is then performed to determine if the material is thermally unstable. In addition to the CRT being significantly more severe and quantitative, there are significant other advantages for using the CRT.

Book Synopsis Indoor Allergens by : National Research Council
Download or read book Indoor Allergens written by National Research Council and published by National Academies Press. This book was released on 1993-02-01 with total page 321 pages. Available in PDF, EPUB and Kindle. Book excerpt: More than 50 million Americans, one out of five, suffer from hay fever, asthma, and other allergic diseases. Many of these conditions are caused by exposure to allergens in indoor environments such as the house, work, and schoolâ€"where we spend as much as 98 percent of our time. Developed by medical, public health, and engineering professionals working together, this unique volume summarizes what is known about indoor allergens, how they affect human health, the magnitude of their effect on various populations, and how they can be controlled. The book addresses controversies, recommends research directions, and suggests how to assist and educate allergy patients, as well as professionals. Indoor Allergens presents a wealth of information about common indoor allergens and their varying effects, from significant hay fever to life-threatening asthma. The volume discusses sources of allergens, from fungi and dust mites to allergenic chemicals, plants, and animals, and examines practical measures for their control. Indoor Allergens discusses how the human airway and immune system respond to inhaled allergens and assesses patient testing methods, covering the importance of the patient's medical history and outlining procedures and approaches to interpretation for skin tests, in vitro diagnostic tests, and tests of patients' pulmonary function. This comprehensive and practical volume will be important to allergists and other health care providers; public health professionals; specialists in building design, construction, and maintenance; faculty and students in public health; and interested allergy patients.
Book Synopsis Energetic Materials at Extreme Conditions by : David I.A. Millar
Download or read book Energetic Materials at Extreme Conditions written by David I.A. Millar and published by Springer Science & Business Media. This book was released on 2011-09-24 with total page 222 pages. Available in PDF, EPUB and Kindle. Book excerpt: David I.A. Millar's thesis explores the effects of extreme conditions on energetic materials. His study identifies and structurally characterises new polymorphs obtained at high pressures and/or temperatures. The performance of energetic materials (pyrotechnics, propellants and explosives) can depend on a number of factors including sensitivity to detonation, detonation velocity, and chemical and thermal stability. Polymorphism and solid-state phase transitions may therefore have significant consequences for the performance and safety of energetic materials. In order to model the behaviour of these important materials effectively under operational conditions it is essential to obtain detailed structural information at a range of temperatures and pressures.
