Petrone and published by . This book was released on 1967 with total page 9 pages. Available in PDF, EPUB and Kindle. Book excerpt: The report describes an investigation made in order to determine the validity of the classical model for the detonation structure of condensed phase explosives in view of recent contradictory evidence, determine any effect of the complex wave interactions of the reflected shock and rarefaction waves within the reaction zone on the measured free surface velocities of the shocked metal, an effect which has previously been neglected, and remove the anomaly of the 'decay' zone.

This book was released on 2022-12-16 with total page 281 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book highlights the theories and research progress in gaseous detonation research, and proposes a universal framework theory that overcomes the current research limitations. Gaseous detonation is an extremely fast type of combustion that propagates at supersonic speed in premixed combustible gas. Being self-sustaining and self-organizing with the unique nature of pressure gaining, gaseous detonation and its gas dynamics has been an interdisciplinary frontier for decades. The research of detonation enjoyed its early success from the development of the CJ theory and ZND modeling, but phenomenon is far from being understood quantitatively, and the development of theories to predict the three-dimensional cellular structure remains a formidable task, being essentially a problem in high-speed compressible reacting flow. This theory proposed by the authors’ research group breaks down the limitation of the one-dimensional steady flow hypothesis of the early theories, successfully correlating the propagation and initiation processes of gaseous detonation, and realizing the unified expression of the three-dimensional structure of cell detonation. The book and the proposed open framework is of high value for researchers in conventional applications such as coal mine explosions and chemical plant accidents, and state-of-the-art research fields such as supernova explosion, new aerospace propulsion engines, and detonation-driven hypersonic testing facilities. It is also a driving force for future research of detonation.

This book was released on 1991-08-31 with total page 300 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of late the demands of industry in creating new composite and functional materials with present properties stimulated an increased interest to the investigation of processes which occur in the detonation technologies of complex chemical composition with an additive of disperse particles. The collection includes a series of papers presented at the 3d International Conference "Lavrentyev Readings on Mathematics, Mechanics, and Physics" (Novosibirsk, 1990),was held by the Hydrodynamics Institute under the support of the Presidium of the Siberian Branch of the USSR Academy of Sciences to stimulate the international cooperation of the leading international centers. In the framework of this Conference the Round Table seminar was held by Prof. A. Borissov and Prof. V. Mi trofanov devoted to "Dynamic Structure of Detonation in Gaseous and Dispersed Media". The idea to hold such Round Table was supported by Chairman of Organizing Committee academician Prof. V.Titov from Hydrodynamics Institute, and academician Prof. V. Nakoryakov and also his Institute of Thermophysics. The main ideas discussed at the Round Table were presented in the form of papers which reflected present situation of the problem of dynamic structure of the detonation waves in gaseous and dispersed media. The basic experimental facts concerning of complicated mul ti dimensional non-stationary structure both of the detonation wave and its front surface, generation of the cell structure, the effect of transverse waves, obstacles, channel geometry etc. on the transition from dynamic regime to stationary structure are represented in the fist three papers.

This book was released on 2012-03-28 with total page 482 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book, as a volume of the Shock Wave Science and Technology Reference Library, is primarily concerned with the fundamental theory of detonation physics in gaseous and condensed phase reactive media. The detonation process involves complex chemical reaction and fluid dynamics, accompanied by intricate effects of heat, light, electricity and magnetism - a contemporary research field that has found wide applications in propulsion and power, hazard prevention as well as military engineering. The seven extensive chapters contained in this volume are: - Chemical Equilibrium Detonation (S Bastea and LE Fried) - Steady One-Dimensional Detonations (A Higgins) - Detonation Instability (HD Ng and F Zhang) - Dynamic Parameters of Detonation (AA Vasiliev) - Multi-Scaled Cellular Detonation (D Desbordes and HN Presles) - Condensed Matter Detonation: Theory and Practice (C Tarver) - Theory of Detonation Shock Dynamics (JB Bdzil and DS Stewart) The chapters are thematically interrelated in a systematic descriptive approach, though, each chapter is self-contained and can be read independently from the others. It offers a timely reference of theoretical detonation physics for graduate students as well as professional scientists and engineers.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Two-dimensional simulation results are presented that capture at great detail the temporal evolution of Mach reflection triple point sub-structures intrinsic to gaseous detonation waves. The observed patterns are classified by shock polar analysis for realistic, thermally perfect but nonreactive gases. A diagram of the transition boundaries between possible Mach reflection structures is constructed and found to be in good agreement with the computational results.

Available in PDF, EPUB and Kindle. Book excerpt: The major portion of this report is devoted explicitly to the study of the standing detonation wave in a hydrogen-air mixture. The experimental arrangement and procedures employed are briefly described and the experimental results presented. A revised analysis of the ignition delay zone behind the shock is presented which handles the equations more rigorously than an earlier treatment. The prediction of the time rate of growth of concentrations of the radicals behind the shock is found to be slightly different than an earlier analysis but the prediction of ignition time delay is unchanged. Vibrational relaxation is considered insofar as it affects the ignition time delay. Preliminary measurements aimed at probing the combustion region of the detonation wave by means of a sodium D-line reversal technique are described. A consideration of some probable two dimensional effects behind the shock reveal a likely explanation of some hitherto uncertain anomalous ignition delay measurements.

Available in PDF, EPUB and Kindle. Book excerpt: 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 acknow 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.
