The strength of the reflected shock wave
is weaker than the incident shock.
The interaction between reflected shock wave and boundary layer could cause slight rise of pressure before the ignition.
In present study, the ignition delay times of 25DHF were measured behind reflected shock waves and the simulation of experiment based on Liu model was carried out.
The ignition delay data for the present study was collected behind the reflected shock waves.
The ignition delay times of 25DHF were measured behind reflected shock waves at the pressures of 4, 10atm, temperatures of 1110-1650K, for the lean ([phi] = 0.
Figures 3(a) and 3(b) show the scenarios of the interaction between the incident shock wave and the spherical flame, while Figures 3(c) and 3(d) correspond to the interaction between the reflected shock wave and the distorted flame.
However, the P value has a larger scope and a more gentle change behind the reflected shock wave (t = 501 [micro]s) than that behind the incident shock wave (t = 189 [micro]s).
Therefore, Figures 6 and 7 imply that the distorted flame exhibits the characteristic of large-scale turbulence combustion, especially for the flame behind the reflected shock wave, which appears to have a more standard teardrop shape, and this indicates that the small scales of the turbulence have become more developed in the flame zone behind the reflected shock wave.
At different measuring points, influence of water surface and underwater reflected shock wave
Symes, both mathematicians at Rice University in Houston, report a new analytical method for estimating the energy of the explosion and the characteristics of the reflected shock wave
The reflected shock wave
further compresses and heats up gas already jazzed by a violent encounter with the original, outgoing shock wave.
At this time, t = 208 [micro]s, after the incident shock hits the sphere one can see clearly the incident and the reflected shock waves
