Investigation of Spinning Detonation and Detonation Stability

The Physics of Fluids, 1961
The stability of a detonation wave and the nature of a spinning detonation have been investigated by observing the patterns inscribed by the wave in soot coatings on films located on the circumference of the detonation tube and on the end plate. The detonation instability reported by others persists to an initial pressure of over 2 atm and to wave ...

Gaseous Detonation. I. Initiation of Detonation

The Journal of Chemical Physics, 1951
By means of piezoelectric gauges, a study has been made of the development of detonation from a shock wave propagated into a mixture. With a sufficiently strong shock, detonation above the stable velocity is immediately established which decays smoothly to the steady state. When the shock is weaker than required for detonation the phenomena which ensue

Multicyclic Detonation Initiation Studies in Valveless Pulsed Detonation Combustors

42nd AIAA/ASME/SAE/ASEE Joint Propulsion Conference & Exhibit, 2006
A pulsed detonation combustor was developed with the total absence of mechanical valves. The device was operated over a range of conditions with air and gaseous fuels (ethylene and propane) with both fuel streams and airstreams operating in valveless mode.

Change in Continuous Detonation Wave Propagation Mode from Rotating Detonation to Standing Detonation

Chinese Physics Letters, 2010
We perform a three-dimensional numerical simulation based on a one-step chemical reaction model to investigate changes in the mode of H2-Air detonation wave propagation from rotating detonation wave (RDW) mode to standing detonation wave mode. The physical characteristics of an RDW with injection velocity of 500m/s are analyzed to investigate the ...

Multiphase Detonations for Pulse Detonation Rocket Engines

2002
Abstract : Recent efforts in PDRE research at AFRL-West have focused on basic studies of the detonation or constant-volume combustion of multiphase mixtures. A collaborative effort is under way for developing models appropriate for PDRE application studies.

Detonation !

A detonation is an explosion driven by energy released behind a leading shock wave traveling through a background of energetic material. It is the strongest form of combustion wave, travels orders of magnitude faster than a flame, and once it is started, it is difficult to impossible to contain until all of the fuel is consumed.
