This is a transient state where the detonation wave overshoots its steady state velocity.
The distance from ignition to the formation of a steady detonation wave is known as the "run-up distance.
The highly localized, transient pressure peak associated with a detonation wave results in distinctive crack propagation patterns.
When a pipe fails under detonation loading, two cracks propagate away from the initiation point, one in the direction of the detonation wave propagation (forward) and one in the opposite direction (backward).
The attachment of the flap to the receiver side suggests that the detonation wave that ruptured the pipe was propagating from the pig receiver toward the pig launcher.
Pulse detonation wave
engines will propel a vehicle at high speeds by harnessing the shockwaves created during the ignition of the fuel charge.
The point of ignition and ignition explosive Semtex was selected in such a manner that the detonation wave
would be directed approximately in parallel with material length.
Once a detonation wave
begins, it keeps expanding outwards," said Flynn.
The front of detonation wave
forms an angle y with an edge of primary charge (Fig.
The have come up with a formula of 'phantom' jams, based on the equations that describe detonation waves caused by explosions.
Aslan Kasimov, a lecturer at MIT's department of mathematics, and the team found that jamitons behave like detonation waves in that they have a 'sonic point', a sort of bottleneck, which separates the traffic flow into upstream and downstream areas.
