WebThe shock propagation theory of Brinkley & Kirkwood (1947) is extended to provide a uniformly valid analytic solution of point-explosion problems both when the undisturbed … 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.

WebJan 22, 2015 · Blast wave propagation in the air is governed by three fundamental equations of fluid dynamics: mass conservation, momentum conservation, and energy conservation equations. These three equations can be combined to yield the Navier-Stokes equation that governs the blast wave propagation in the air [ 17 ].
