WebMay 13, 2024 · A new scaling is developed for both air and underwater blast waves based on dimensional analysis. The new length, time, velocity, and pressure scales are based on three control parameters: the energy release of the explosive \(E_{_\mathrm {HE}}\), the density of the undisturbed ambient medium \(\rho _{_0}\), and the speed of sound in the … WebOct 28, 2005 · Underwater explosions are conventionally identified and characterized by their seismic and/or acoustic signature based on spherical models of explosion bubbles. These models can be misleading in cases where the bubble is distorted by proximity to the free surface, the bottom, or to a solid object. An experimental and numerical study of the …
WebTrinitrotoluene (TNT) is commonly used to generate, characterize, and study underwater explosions. TNT has a specific energy of 4500 kJ/kg and the specific energy released by … WebIf the initial position of the explosive reaches a certain depth, that is, γ f < − 8, the bubble generated by the explosion will no longer be broken but a complete underwater explosion bubble. Fig. 17 shows the bubble’s evolution process generated by the explosion of the 500 kg spherical TNT explosive when γ f = −16.
WebThis rapidly expanding gas, called a pressure wave, is the key to any explosive's destructive power. If the pressure wave is fast enough to break the sound barrier, it generates a powerful shock wave.
