Investigations on Deflagration to Detonation Transition

4 simplified model that can predict the transition from compaction to detonation and shock to detonation is given with the uim of describing experiments in beds of porous HMX. In the case of compaction to detonation. the energy of early impact generates a slowly moving. convectivereactive deflagration that expands near the piston face and evolves in a manner that is characteristic of confined d...

Theoretical Analysis on Deflagration-to-Detonation Transition

The study on deflagration-to-detonation transition (DDT) is very important because this mechanism has relevance to safety issues in industries, where combustible premixed gases are in general use. However, the quantitative prediction of DDT is one of the major unsolved problems in combustion and detonation theory to date. In this paper, the DDT process is studied theoretically and the critical ...

Transition from Deflagration to Detonation in Layered Dust Explosions

Dust layers on the bottom of mine tunnels, on fac toy floors, or on the floors of gruin elevator passages are the most frequent cause of highly destructive dust explosions. Typically, such layered dust explosions involve a high velocity, acceleruting, turbulent flame which is fed by the dust layer and results in high clestructivt' static and dynamic pressures. In some cases transition to detona...
