- New techniques to slow down convective burning and low-velocity detonation, stabilize them, and control their properties, particularly the transition to normal detonation
- Applications for reducing risks of accidental ignition of energetic materials
- Investigates compacted modified propellants to increase performance of guns, especially with a traveling charge
- Designs for low-velocity detonation as a working model for pulse-nozzle and missile devices and to generate enhanced blast waves
This book presents original research into the behavior, ignition mechanisms, and wave structure of convective burning and low-velocity detonations (LVDs). Such processes occupy an intermediate position between modes of normal combustion and normal detonation, and their properties directly affect the dynamics of explosions, including unplanned explosions caused by accidental ignition. The book illustrates techniques to stabilize convective burning and LVDs and control their properties, thus enabling energetic materials specialists and ballistics experts to manage potentially dangerous hazards of transition to normal detonation. In addition, the book provides a scientific foundation for the technical application of these processes in pulse-nozzle and missile devices and in jet injectors. It also offers new studies on compacted modified propellants, which, due to their burning mechanisms, can significantly enhance the performance of barrel systems.
From the Foreword
…Sulimov and Ermolaev are world experts in understanding the conditions by which transitions from combustion to convective burning and low velocity detonations occur. Sulimov has been active in this area since the 1970s when he co-authored the book entitled “Transition from Deflagration to Detonation in Condensed Phases.”
This new book, on “Convective burning and low-velocity detonation of porous media” comprises an Introduction on the deflagration-to-detonation transition in solids. The remainder is split into two parts. Part 1 covers fundamental properties of convective burning and low-velocity detonation. Part 2 covers the application of convective burning and low-velocity detonation in pulse engineering devices.
In the book chapters the authors expound upon the theory and design of charge concepts that utilise convective burning and low-velocity detonation. This is applied to increase the launcher loading density to nearly 1.4g/cc, achieving a launcher muzzle velocity increase in excess of 20%. This theoretical work is strongly supported by experiments.
Convective Burning and Low-Velocity Detonation in Porous Media should be of considerable interest to scholars, engineers and scientists who are working in the area of the combustion of porous energetic materials. I highly commend it to the reader.
