Book Description
This unique book is a store of less well-known explosion anddetonation phenomena, including also data and experiences related tosafety risks. It highlights the shortcomings of the currentengineering codes based on a classical plane wave model of thephenomenon, and why these tools must fail. For the first time all the explosion phenomena are described in termsof proper assemblages of hot spots, which emit pressure waves andassociated near field terms in flow. Not all of the approaches arenew. Some even date back to the 19th century or earlier.. What is newis the application of these approaches to explosion phenomena. Inorder to make these tools easily available to the current detonationphysicist, basic acoustics is therefore also addressed. Whereas the current plane wave, homogeneous flow detonation physicsis an excellent engineering tool for numerical predictions undergiven conditions, the multi-hot-spot-model is an additional tool foranalyzing phenomena that cannot be explained by classicalcalculations. The real benefit comes from being able to understand,without any artificial assumptions, the whole phenomenology ofdetonations and explosions. By specifying pressure generatingmechanisms, one is able to see that the current treatment of thedetonics of energetic materials is only a very special - but powerful- case of explosion events and hazards. It becomes clear thatphysical explosions must be taken into account in any safetyconsiderations. In these terms it is easy to understand why evenliquid carbon dioxide and inert silo materials can explode. A unique collection of unexpected events, which might surprise evenspecialists, has resulted from the evaluation of the model. Thereforethis book is valuable for each explosion and safety scientist for theunderstanding and forecasting of unwanted events. The text mainlyaddresses the next generation of explosion and detonation scientists,with the goal of promoting the science of detonation on a newphysical basis. For this reason gaps in current knowledge are alsoaddressed. The science of explosions is not fully mature, but isstill in its beginning - and the tools necessary for furthering theunderstanding of these phenomena have been with us for centuries.

Book Description
A detonation theory based on a microscopic model of a solid has been developed. This was accomplished by considering known physical and chemical properties of the individual molecules in the system. The results show that molecular vibrational energies, normal lattice frequencies and activation energies are the most important parameters in the model. Molecules having low vibrational energies are easier to detonate, according to the theory, because of the ease of creation of a population inversion or 'hot spot' in the system. A 'perfect crystal' would be more difficult to detonate because initiation would occur at one of the faces. However, the model shows that perfect crystals of unstable solids cannot be grown. Consequently, detonation in any real crystal will be initiated in the interior near a defect. The present model explains many experimental observations that cannot be explained on the basis of older theories of detonation. For example, the microscopic theory can easily explain the occurrence of explosions during growth of crystals from solutions. (Author).

Book Description
For a chemist who is concerned with the synthesis of new energetic compounds, it is essential to be able to assess physical and thermodynamic properties, as well as the sensitivity, of possible new energetic compounds before synthesis is attempted. Various approaches have been developed to predict important aspects of the physical and thermodynamic properties of energetic materials including (but not limited to): crystal density, heat of formation, melting point, enthalpy of fusion and enthalpy of sublimation of an organic energetic compound. Since an organic energetic material consists of metastable molecules capable of undergoing very rapid and highly exothermic reactions, many methods have been developed to estimate the sensitivity of an energetic compound with respect to detonationcausing external stimuli such as heat, friction, impact, shock and electrostatic discharge. This book introduces these methods and demonstrates those methods which can be easily applied.
