RESEARCH ON DETONATION WAVE MECHANICS.
Abstract
An analysis leading to an extension of the Taylor-Stanyukovich simularity solution for detonation waves having circular symmetries is given. The extension utilizes the continuum mechanical field equations written in intrinsic coordinate form without approximation. The resulting extended Taylor-Stanyukovich solution allows for the prediction of more general wave shapes in infinite explosive slabs and more general waves of revolution in infinite explosive half spaces. The restrictions applied are that self similar flow exist and that the flow be irrotational on both sides of the shock front. Implications of these restrictions are discussed. The predicted wave shapes are then compared with high speed framing camera photographs of detonation waves in several explosive materials and under a variety of initiation conditions. A very excellent agreement of theory and experiment is observed. Extrapolation to non-similar regions as well as certain non-steady detonations show the agreement to persist. Agreement is also observed with results presented by other investigators. Some of the data permit a calculation of particle velocity in one region and a value of 0.158 U results from the estimate.
