Direct Initiation of Detonation

Abstract

This study is both a theoretical and experimental investigation of the initiation of detonation by non-ideal blast waves. The theoretical portions consisted of two studies: (1) an analytic study of the flow fields associated with heat addition during the initial phases of heat addition to a source region which is chemically reactive, and (2) a study of the initiation of explosions by nonideal sources using a numerical technique. The analytic portion of this study uncovered many difficulties with the handling of the heat addition in a reactive source region. These are discussed extensively in this report. The numerical calculation showed that when the source region was a bursting sphere of high energy density the total energy in the sphere was the limiting factor for initiation and that when the energy density, of the sphere was low the energy density was the limiting factor for initiation.
