Abstract
The pseudo‐reaction zone model was proposed to improve engineering scale simulations with high explosives that have a slow reaction component. In this work an extension of the pseudo‐reaction zone model is developed for non‐ideal explosives that propagate well below the steady‐planar Chapman‐Jouguet velocity. A programmed burn method utilizing Detonation Shock Dynamics (DSD) and a detonation velocity dependent pseudo‐reaction rate has been developed for non‐ideal explosives and applied to the explosive mixture of ammonium nitrate and fuel oil (ANFO). The pseudo‐reaction rate is calibrated to the experimentally obtained normal detonation velocity—shock curvature relation. Cylinder test simulations predict the proper expansion to within 1% even though significant reaction occurs as the cylinder expands.
