What is The Effects of Containment on Detonation Velocity about?

## Abstract Reactive flow cylinder code runs on six explosives were made with rate constants varying from 0.03 to 70 μs^−1^. Six unconfined/steel sets of original ANFO and dynamite data are presented. A means of comparing confinement effects both at constant radius and at constant detonation velocity is presented. Calculations show two qualitatively different modes of behavior. For __U__~__s__~/__C__~__o__~≥1.2, where __U__~__s__~ is the detonation velocity and __C__~__o__~ the zero‐pressure sound speed in steel, we find a sharp shock wave in the metal. The shock passes through the steel and the outer wall has a velocity jump‐off. For __U__~__s__~/__C__~__o__~≤1.04, we find a pressure gradient that moves at the detonation velocity. A precursor pulse drives in the explosive ahead of the detonation front. The outer wall begins to move outward at the same time the shock arrives in the explosive, and the outer wall slowly and continuously increases in velocity. The __U__~__s__~/__C__~__o__~≥1.2 cylinders saturate in detonation velocity for thick walls but the __U__~__s__~/__C__~__o__~<<1.04 case does not. The unconfined cylinder shows an edge lag in the front that approximately equals
