Detonation propagation characteristics of superposition explosive materials
Journal of Wuhan University of Technology-Mater. Sci. Ed., 2003In order to investigate detonation propagation characteristics of different charge patterns, the detonation velocities of superposition strip-shaped charges made up of a detonating cord and explosives were measured by a detonation velocity measuring instrument under conditions of different ignition.

Characteristics of cellular structure of detonation waves propagating in annular channels
Physics of Fluids, 2023This study investigates the characteristics of stable and unstable cells and wavefronts of detonation waves propagating in annular channels with different inner radii and channel widths using two-dimensional Euler equations along with a two-step induction-exothermic reaction kinetics.

Propagation Characteristics of Detonation-Generated Plasmas
Journal of Applied Physics, 1959Studies are presented showing the electrical properties of the highly ionized, detonation-generated plasmas ejected into various gaseous media at the bare surfaces of high explosives. These external plasmas are shown to originate from chemionization in the reactions of high explosive at free surfaces and are not produced by thermal ionization in the ...

Methane–oxygen detonation characteristics near their propagation limits in ducts
Fuel, 2016Abstract In this study, the near-limit behavior of gaseous detonations in three methane–oxygen mixtures (CH 4 –2O 2 , CH 4 –1.5O 2 and CH 4 –4O 2 ) is investigated experimentally. A 36-mm diameter circular tube and three annular channel gaps ( w = 2 mm, 4.5 mm and 7 mm) were used to look at the effect of different geometries on the detonation ...

Effects of the combustor width on propagation characteristics of rotating detonation waves
Aerospace Science and Technology, 2020Abstract To investigate effects of the combustor width on propagation characteristics and initiation processes of rotating detonation waves, this experimental study has been performed in a laboratory-scale rotating detonation combustor. Five combustor widths, including 8 mm, 11 mm, 15 mm, 19 mm, and a hollow case, have been considered, based on a ...

Experimental Thermal and Fluid Science, 2021
Abstract In a rotating detonation engine, detonation waves propagate in the combustor chamber with one side unconfined which will introduce lateral relief and, therefore, results in deficits of the propagation velocity and the peak pressure. To study the critical mixture height for detonation propagation, a simple combustor without considering the ...

Characteristic regimes of multifront-detonation propagation along a convex surface
Combustion, Explosion, and Shock Waves, 1999Experimental results of multifront-detonation diffraction on a convex curvilinear surface are given. An estimate of the minimum gas-layer thickness, which is necessary for the external circumferential rotation of a multifront wave, is proposed.
