Shock Waves, Explosions, and Detonations

Abstract

Shock wave interactions are considered, taking into account the study of shock-induced signals and coherent effects in solids by molecular dynamics, oblique shock waves in two-phase flow, equilibrium shock wave properties in dusty and clean air, shock waves in water induced by focused laser radiation, the ignition of small particles behind shock waves, the reflection of shock waves at rigid walls in two-phase media, and relaxation phenomena in a foamy structure. Topics related to blast waves are discussed, giving attention to self-similar blast waves incorporating deflagrations of variable speed, an analysis of reactive blast waves propagating through gaseous mixtures with spatially distributed chemical energy, the use of general equations of state in similarity analysis of flame-driven blast waves, optical interferometry of spherical shock waves, and the Taylor instability of contact boundary between expanding detonation products and a surrounding gas. Subjects concerned with gaseous detonations, heterogeneous detonations, and explosions in solids are also studied.
