Nuclear Shock Wave Propagation through Air Entrainment Systems of Hardened Facilities

Abstract

An analytical study was undertaken to develop the capability of predicting nuclear shock wave propagation through air entrainment systems of hardened facilities. All solutions presented in this report are one- dimensional. Two finite-difference schemes for approximately the hyperbolic partial differential equations of fluid dynamics are used: the pseudo-viscosity scheme in a variable area Lagrange formulation, and the Lax-Wendroff two-step scheme in an Eulerian formulation. Shock wave attenuation due to viscous losses at ducting walls is included. A comparison of the results of the analysis with shock tube experimental data shows both formulations to be adequate.
