A Gas Dynamics Gurney Analysis for Modeling. The Acceleration History of an Exploding System

Abstract

The Gurney method was originally developed to estimate terminal velocities imparted to metals by explosives, and was subsequently used to correlate exploding foil system performance with firing circuit electrical parameters. The inclusion of internal energy in the explosive gas permits calculation of the acceleration history of the system. Comparison with experimental and hydrocode results indicates that proper selection of initial displacement, velocity, and the polytropic gas exponent can bring model and experimental results into close agreement.
