Two-phase reaction model of a gas-aluminum particles mixture detonation

Gas Detonation Forming by a Mixture of H2+O2 Detonation

Explosive forming is one of the unconventional techniques in which, most commonly, the water is used as the pressure transmission medium. One of the newest methods in explosive forming is gas detonation forming which uses a normal shock wave derived of gas detonation, to form sheet metals. For this purpose a detonation is developed from the reaction of H2+O2 mixture in a long cylindrical detona...

Gas-phase detonation propagation in mixture composition gradients.

The propagation of detonations through several fuel-air mixtures with spatially varying fuel concentrations is examined numerically. The detonations propagate through two-dimensional channels, inside of which the gradient of mixture composition is oriented normal to the direction of propagation. The simulations are performed using a two-component, single-step reaction model calibrated so that o...

A Hybrid Two-Phase Mixture Model of Detonation Diffraction with Compliant Confinement

A multi-material two-phase hybrid model of heterogeneous explosives, with a reaction rate that is proportional to the gas-phase pressure excess above an ignition threshold, is examined computationally. The explosive is confined within a compliant inert, and the focus is on the behavior of an established detonation as it rounds a 90◦ corner and undergoes diffraction. The numerical approach, a va...
