WebAt 50 seconds after the explosion, when the fireball is no longer visible, the blast wave has traveled about 12 miles. It is then traveling at about 784 miles per hour, which is slightly faster than the speed of sound at sea level. Peak overpressure Maximum Wind Speed; 50 psi: 934 mph: 20 psi: 502 mph: 10 psi: 294 mph: 5 psi: Blast waves cause damage by a combination of the significant compression of the air in front of the wave (forming a shock front) and the subsequent wind that follows. A blast wave travels faster than the speed of sound and the passage of the shock wave usually lasts only a few milliseconds. Like other types of … See more In fluid dynamics, a blast wave is the increased 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, … See more High-order explosives (HE) are more powerful than low-order explosives (LE). HE detonate to produce a defining supersonic over … See more The simplest form of a blast wave has been described and termed the Friedlander waveform. It occurs when a high explosive detonates in a free field, that is, with no surfaces nearby with which it can interact. Blast waves have properties predicted by the See more • Chapman–Jouguet condition • Taylor–von Neumann–Sedov blast wave • Zeldovich–Taylor flow See more The classic flow solution—the so-called Taylor–von Neumann–Sedov blast wave solution—was independently devised by John von Neumann and … See more Bombs In response to an inquiry from the British MAUD Committee, G.

WebA nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction. The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion ... WebSince the thermal radiation travels at roughly the speed of light, the flash of light and heat precedes the blast wave by several seconds, just as lightning is seen before thunder is heard. The visible light will produce "flashblindness" in people who are looking in the direction of the explosion. Flashblindness can last for several minutes ...
