Shock Wave Interaction with a Flame
Shock wave/fire interactions initiated by high explosives have been historically demonstrated as potentially effective ways to control oil well fires or even forest fires in situations where conventional means cannot be applied. However, the mechanisms by which a fire can be extinguished by a shock wave are not well understood. A series of experiments have been conducted involving a moving shoc...
متن کاملExplosive-driven shock wave and vortex ring interaction with a propane flame
Experiments were performed to analyze the interaction of an explosively driven shock wave and a propane flame. A 30 g explosive charge was detonated at one end of a 3-m-long, 0.6-m-diameter shock tube to produce a shock wave which propagated into the atmosphere. A propane flame source was positioned at various locations outside of the shock tube to investigate the effect of different strength s...
متن کاملPlanar Detonation Wave Initiation in Large-Aspect-Ratio Channels
P LANAR detonation waves are often created in narrow rectangular channels to more easily visualize the cellular structure of gaseous detonation waves [1–6]. Typically, these detonation waves are initiated from a single high-energy source requiring several kilojoules of input energy, such as a strong spark or exploding wire that creates a spherically or cylindrically expanding wave. This wave is...
متن کاملExtracorporeal shock waves act by shock wave-gas bubble interaction.
The effect of extracorporeal shock waves on hemoglobin release from red blood cells was recently found to be minimized under minute static excess pressure. It was proposed that this can be explained by shock wave-gas bubble interaction. We substantiated this further by two experiments by applying shock waves to suspended human RBC in a lithotripter at a lower frequency (1 pulse every 5 s) and b...
متن کاملDetermining Shock and Detonation Wave PropagationTime Using Wavelet Methods
The propagation speed of a shock or detonation wave in a shock or detonation tube is usually determined by a time-of-flight method by dividing the distance between two transducers with the propagation time of the disturbance signal. Some arbitrariness is inherent in determining the propagation time by this method. A new method based on Haar and Morlet wavelet transforms is reported. The method ...
