It is known that the Chapman-Jouguet theory of detonation is based on the assumption of an instantaneous and complete transformation of explosives into detonation products in the wave front. Therefore, one should not expect from the theory any interpretations of the detonation limits, such as shock initiation of det onation and kinetic instability and propagation (failure diameter). The Zeldovich-Von Neuman-Doring (ZND) theory of detonation appeared, in fact, as a response to the need for a theory capable of interpreting such limits, and the ZND detonation theory gave qualitative interpretations to the detonation limits. These interpretations were based essentially on the theoretical notion that the mechanism of explosives transformation at detonation is a combustion of a layer of finite thickness of shock-compressed explosive behind the wave shock front with the velocity of the front. However, some experimental findings turned out to be inconsistent with the the ory. A very small change of homogeneous (liquid) explosives detonation velocity with explosive charge diameter near the rather sizable failure diameter is one of the findings. The elucidation of the nature of this finding has led to the discovery of a new phenomenon. This phenomenon has come to be known as the breakdown (BD) of the explosive self-ignition behind the front of shock waves under the effect of rarefaction waves.

My introduction to the fascinating phenomena associated with detonation waves came through appointments as an external fellow at the Department of Physics, University College of Wales, and at the Department of Mechanical Engineering, University of Leeds. Very special thanks for his accurate guidance through the large body of information on gaseous detonations are due to Professor D.H. Edwards of University College of Wales. Indeed, the onerous task of concisely enumerating the key features of unidimensional theories of detonations was undertaken by him, and Chapter 2 is based on his initial draft. When the text strays to the use of we, it is a deserved acknowƯ ledgement of his contribution. Again, I should like to thank Professor D. Bradley of Leeds University for his enthusiastic encouragement of my efforts at developing a model of the composition limits of detonability through a relationship between run-up distance and composition of the mixture. The text has been prepared in the context of these fellowships, and I am grateful to the Central Electricity Generating Board for its permission to accept these appointments.

This work marks a stage in the evolution of a scientific and technical field which has been developed by the Commissariat a l'Energie Atomique (CEA) over several decades. Many members of the staff of the CEA have won re nown in this field, and their work has brought it to the high degree of excel lence for which it is internationally recognized today. These scientists had to consider every aspect of the field, as it concerned: modeling, which has recourse to fluid thermodynamics, molecular phys ics, and chemistry; numerical evaluation, which relies on mathematical analysis and data processing; and experiments in the firing area, which require specific stress generators and instrumentation. Whilst this book is a testament to the activity and success of staff of the CEA, it also reviews a number ofthe advances made in the discipline. How ever, it is not intended to be an exhaustive account of those advances; it is assumed that the reader can, if desired, consult the standard monographs, and more recent, more specialized works (notably W.C. Davis and W. Fickett, and C.L. Mader). The history of the discipline is interesting in itself, and also as an illustra tion of the causes which lead to progress in a coherent body of scientific work. I should like to make some comments on this progress, of which there is a fascinating summary in the introduction, and which will figure largely throughout the work.

This book introduces the detonation phenomenon in explosives. It is ideal for engineers and graduate students with a background in thermodynamics and fluid mechanics. The material is mostly qualitative, aiming to illustrate the physical aspects of the phenomenon. Classical idealized theories of detonation waves are presented first. These permit detonation speed, gas properties ahead of and behind the detonation wave, and the distribution of fluid properties within the detonation wave itself to be determined. Subsequent chapters describe in detail the real unstable structure of a detonation wave. One-, two-, and three-dimensional computer simulations are presented along with experimental results using various experimental techniques. The important effects of confinement and boundary conditions and their influence on the propagation of a detonation are also discussed. The final chapters cover the various ways detonation waves can be formed and provide a review of the outstanding problems and future directions in detonation research.

This unique book is a store of less well-known explosion and detonation phenomena, including also data and experiences related to safety risks. It highlights the shortcomings of the current engineering codes based on a classical plane wave model of the phenomenon, and why these tools must fail. For the first time all the explosion phenomena are described in terms of proper assemblages of hot spots, which emit pressure waves and associated near field terms in flow. Not all of the approaches are new. Some even date back to the 19th century or earlier.. What is new is the application of these approaches to explosion phenomena. In order to make these tools easily available to the current detonation physicist, basic acoustics is therefore also addressed. Whereas the current plane wave, homogeneous flow detonation physics is an excellent engineering tool for numerical predictions under given conditions, the multi-hot-spot-model is an additional tool for analyzing phenomena that cannot be explained by classical calculations. The real benefit comes from being able to understand, without any artificial assumptions, the whole phenomenology of detonations and explosions. By specifying pressure generating mechanisms, one is able to see that the current treatment of the detonics of energetic materials is only a very special - but powerful - case of explosion events and hazards. It becomes clear that physical explosions must be taken into account in any safety considerations. In these terms it is easy to understand why even liquid carbon dioxide and inert silo materials can explode. A unique collection of unexpected events, which might surprise even specialists, has resulted from the evaluation of the model. Therefore this book is valuable for each explosion and safety scientist for the understanding and forecasting of unwanted events. The text mainly addresses the next generation of explosion and detonation scientists, with the goal of promoting the science of detonation on a new physical basis. For this reason gaps in current knowledge are also addressed. The science of explosions is not fully mature, but is still in its beginning - and the tools necessary for furthering the understanding of these phenomena have been with us for centuries.
