This is a unique collection of articles on fundamentals and control of detonations and high-speed deflagrations written by international experts . The book comprises three parts: (1) High-Speed Deflagrations, (2) Detonations, and (3) Pulsed Detonation Engines. The first part deals mainly with various aspects of Deflagration-to-Detonation Transition in gaseous and heterogeneous media and describes high-speed transient regimes of turbulent combustion that are intermediate between detonation and slow deflagration. The emphasis is made on control of pre-detonation distance in confined, partially confined and unconfined conditions by means of obstructions, chemical sensitizers, etc. The second part includes contributions on control of direct detonation initiation and propagation in channels of constant and variable cross section. The third part describes applications of various explosion control techniques to pulsed detonation engines (PDE). New concepts of PDE dealing with 'rotating' detonations, repeated in situ mixing of fuels with different detonability, periodically reinitiated detonations, jet-induced detonations in a resonator, etc. are discussed in detail and evaluated. The comparative studies of the combustion efficiency in various types of thrusters and propulsion power plants are also reported with the emphasis made on the performance of PDE. The book, with numerous illustrations, and extensive list of up-to-date references, is a compilation of outstanding state-of-the-art research in this field that has attracted significant world-wide attention in the past several years.
The volume is addressed to scientists and practicing research engineers working
in the field of propulsion and power engineering. It will be useful as an advanced
graduate level text for courses in deflagration, detonation, and propulsion.
