Blast Wave

A blast wave in fluid dynamics is the pressure and flow resulting from the deposition of a large amount of energy in a small very localised volume. The flow field can be approximated as a lead shock wave, followed by a 'self-similar' subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core. It has a leading shock front of compressed gases. The blast wave is followed by a blast wind of negative pressure, which sucks items back in towards the center. The blast wave is harmful especially when one is very close to the center or at a location of constructive interference. High explosives, which detonate, generate blast waves.

Famous quotes containing the words wave and/or blast:

    Now I stand as one upon a rock,
    Environed with a wilderness of sea,
    Who marks the waxing tide grow wave by wave,
    Expecting ever when some envious surge
    Will in his brinish bowels swallow him.
    William Shakespeare (1564–1616)

    You know, if this is Venus, or some other strange planet, we’re liable to run into some high-domed characters with green blood in their veins who’ll blast at us with their atomic death rayguns, and there we’ll be with these—these poor old-fashioned shootin’ irons.
    Edward L. Bernds (b. 1911)
