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...
متن کاملTheoretical 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 ...
متن کاملTransition 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...
متن کاملDeflagration to Detonation
Thermonuclear explosions of Type Ia supernovae (SNIa) involve turbulent deflagrations, detonations, and possibly a deflagration-to-detonation transition. A phenomenological delayed detonation model of SNIa successfully explains many observational properties of SNIa including monochromatic light curves, spectra, brightness – decline and color – decline relations. Observed variations among SNia a...
متن کاملPlasma-assisted ignition and deflagration-to-detonation transition.
Non-equilibrium plasma demonstrates great potential to control ultra-lean, ultra-fast, low-temperature flames and to become an extremely promising technology for a wide range of applications, including aviation gas turbine engines, piston engines, RAMjets, SCRAMjets and detonation initiation for pulsed detonation engines. The analysis of discharge processes shows that the discharge energy can b...
