Lectures on Detonation Physics: Introduction to the Theory of Detonation ShockDynamics

摘要

These lectures review some basic results of detonation theory and are specializedto serve as an introduction to the theory of Detonation Shock Dynamics (DSD). The theory of DSD is a time dependent, multidimensional theory for the propagation of near Ohapman Jouguet (OJ) detonations. This theory is especially relevant to applications of detonation propagation in condensed explosives and the basic dynamics in freely propagating gaseous explosives as well. The theory that we present is based on rigorous mathematical arguments and rational approximations for an assumed model of the explosive material. The material is described by the compressible, reactive Euler equations for a given equation of state and kinetic rate law for the release of exothermic, chemical energy. This theory is the basis for the engineering Method of Detonation Shock Dynamic, that is now being used in the design of explosive systems. Lectures on the Method of Detonation Shock Dynamics are being planned as a sequel. This first set of lectures were given in the summer of 1992 at Eglin Air Force Base.
