Abstract

We describe how to calibrate the reactive flow model used in the hydrodynamic simulations of explosives with the theory of detonation shock dynamics (DSD). This DSD-informed calibration uses experimental shock Hugoniot data, plane shock initiation data, the data for shock curvature (Dn - κ) relation and diameter effect data as documented in papers [1, 2]. This paper presents a new procedure based on: (1) The sensitivity of parameter values of the reactive flow model to the shock initiation (Pop-plot) and the Dn - κ relation and (2) the comparison of the detonation shock shape obtained from the experiment and theory for a rate stick.
