Title A study of shock front profiles in the deflagration-to-detonation transition
Date 1980-05
Year graduated 1980
Description By application of the equations governing non-Newtonian viscous flow, it has been shown that a cylindrical detonating explosive behaves like a non-Newtonian viscous fluid emerging from a cylindrical pipe. The shape of emerging flame fronts is described by a hyperbolic cosine function; however, a plot of the logarithm of the particle velocity against the logarithm of the radial position indicates that the hyperbolic cosine may be replaced by a parabola within the accuracy of the available experimental data. Data tested was for steady-state shock fronts and transient wave fronts occurring from the time of initiation to the establishment of steady detonation. Furthermore, an analysis of the behavior of several detonation parameters as a function of time in the transient cases showed that the deflagration-to-detonation transition is characterized in part by a nearly discontinuous temperature rise approximately 15 microseconds after initiation.
