peak overpressure

[′pēk ′ō·vər‚presh·ər]
(ordnance)
The highest overpressure resulting from a blast wave; peak overpressures near the fireball of an atomic explosion are very high but drop off rapidly as the blast wave travels along the ground outward from ground zero.

Peak overpressure will usually be different on each face of the building with the highest being on the face directly opposing the blast source.
Properly select the blast damper for the specific blast peak overpressure and impulse duration of the project.
Both types of exit boundary conditions produce the same peak overpressure strength, because the duct is long enough to develop a normal shock capable of yielding the same strength at the throat as a normal shock generated at the engine face.
A comparison between the 3-D CFD results to the existing F-16 characteristic overpressure ratio distribution shows that the peak inlet overpressure distribution is a collation of peak magnitudes of the hammer-shock waveform along the NSI duct, while the peak overpressure ratio is calculated at every station and normalized by the engine-face overpressure ratio.
