Blast wave propagation
WebTo evaluate the accuracy of the kinetic mechanism and the validity of the simulation of the volumetric explosions, including the blast wave propagation and its interaction with the walls, the explosion of a certain volume of stoichiometric propane/oxygen mixture in a semi-confined volume is investigated and the numerical results are compared ... 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, followed by a self-similar subsonic flow field. In simpler terms, a blast wave is an area of pressure … See more High-order explosives (HE) are more powerful than low-order explosives (LE). HE detonate to produce a defining supersonic over-pressurization shock wave. Several sources of HE include trinitrotoluene See more The classic flow solution—the so-called Taylor–von Neumann–Sedov blast wave solution—was independently devised by John von Neumann and British mathematician See more Blast waves cause damage by a combination of the significant compression of the air in front of the wave (forming a shock front) … See more • Chapman–Jouguet condition • Taylor–von Neumann–Sedov blast wave • Zeldovich–Taylor flow See more The simplest form of a blast wave has been described and termed the Friedlander waveform.

WebThis distance should correspond to the distance that the blast wave travels during its time of application, which can be checked by a simple calculation. If the length of the wave front is 0.2 m and the wave speed is 5.15 в 10 3 m/s, the time it takes for the wave to travel 0.2 m is 3.88 в 10 –5 s. As expected, this is the duration of the ... WebThe primary blast wave—propagation of a supersonic pressure gradient—is elicited from the detonation of an explosive device. In the millisecond range, a chemical reaction releases a high positive pressure wave that expands radially from the blast site, followed by a longer negative pressure phase. This ideal-
