FAB-2D Code Computations of Nuclear Free-Air Blast Waves in a Horizontally Stratified Standard Atmosphere.

Abstract

The FAB-2D two-dimensional hydrodynamic computer code was developed for computing the blast flow characteristics of a nuclear free-air blast wave in a non-homogeneous atmosphere. The flow field is represented by a multi-cell moving grid with fluid properties calculated by Godunov's method. The shock wave at the blast front is represented by the Hugoniot relation. Real air properties are represented by Brode's 1965 equation of state. Thermal radiation is taken into account. (Author)
