Extensions to DSD theory: Analysis of PBX 9502 rate stick data

摘要

Recent extensions to DSD theory and modeling argue that the intrinsic front propagation law can depend on variables in addition to the total shock-front curvature. Here the authors outline this work and present results of high-resolution numerical simulations of 2D detonation that verify the theory on some points, but disagree with it on others. Chief among these is the verification of the extended propagation laws and the observation that the curvature is infinite at the HE boundary. The authors discuss how these results impact the analysis of PBX 9502.
