Propagation of Non-Ideal Detonation Wave Confined by Inert Medium

In order to have an insight into the propagation of non-ideal detonation wave confined by inert medium, the shock polar method relating the pressure/streamline-deflection matching condition at the explosive/inert medium interface was adopted. The detonation front shape and the pressure distribution were calculated by this method combined with detonation shock dynamics (DSD) method and the program describing detonation acceleration. Comparison between experimental data and numerical simulation results shows that although a detailed description for interaction between the detonation wave and the inert medium needs full hydrodynamic simulation in the complete flow field, a relatively simple shock polar analysis can also provide a good prediction of the interaction effect, which is consistent with the argument from Aslam et al. of United States of America.
