      Detonation tube studies of aluminum particles dispersed in air Symposium (International) on Combustion, Vol. 19, No. 1 The reaction zone structure of cylindrical detonations in monodisperse spraysCited by: A detonation wave is a combustion wave propagating at a supersonic speed. It is composed of a leading shock followed by a chemical reaction zone. The leading shock compresses the high-explosive material, and converts the high-explosive into gaseous products .

Subsequent refinements in the theory have been concerned primarily with the structure of the wave. The details of both the classical and the current the- oretical work are presented in modem books such as Hirschfelder, Curtiss, and Bird (10) and Courant and Fried-.

    Detonation (from Latin detonare, meaning 'to thunder down/forth') is a type of combustion involving a supersonic exothermic front accelerating through a medium that eventually drives a shock front propagating directly in front of it. Detonations occur in both conventional solid and liquid explosives, as well as in reactive gases. The velocity of detonation in solid and liquid explosives is.   Structure and initiation of plane detonation waves in a bidisperse gas suspension of aluminum particles Combustion, Explosion, and Shock Waves, Vol. 44, No. 2 Theoretical and numerical study of detonation processes in gas suspensions with aluminum particlesCited by:

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. 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. In contrast to the laminar one-dimensional ZDN model, the three-dimensional cellular structure of homogeneous gaseous detonation has been firmly established. The structure consists of an ensemble of interacting transverse shock waves sustained by the energy release from chemical by: 6.

Unlike gaseous detonation, dust detonation generally requires much longer time (or distance in this study) for transition to detonation because of heterogeneous effects on the two-phase dust (solid)/oxidizer mixtures, which cause longer ignition delays, a longer combustion zone, and corresponding wall by: 8.

Sustor2 provides deep cooling of a gas flow, practically total condensation of a vapor, and fast and effective removal of the condensed liquid with a significantly reduced pressure losses compared with the prior art.

Sustor2 performs the said operations by developing a. The measured parameters were detonation velocities, pressures behind the > detonation waves, and the dynamic strain of the detonation tube. These parameters were also calculated for Chap- man-Jouguet detonation so that velocity and pres- sure deficits in the porous bed could be ascertained and a mechanism for propagation by: 9.

The book is concerned only with detonation waves in gaseous explosives, because they are much better understood than detonations in condensed phase media. There are many similarities between detonations in gaseous and in condensed explosives, in that the detonation pressure of condensed explosives is much higher than the.
