BEERAY, A One-Dimensional Hydrodynamics Code for Strong Shocks.
Abstract
BEERAY, a fast one-dimensional Lagrangian hydrodynamics computer code, is developed from the basic principles of conservation of mass, momentum, and energy for a strong shock propagation in a solid or gas. The code uses two equations of state - the adiabatic ideal gas law and the Gruneisen equation of state with constant Gruneisen ratio for a solid. The conservation equations and the equations of state are expressed as finite difference equations across a spatial mesh composed of up to 100 cells. Results for three problems are presented which show the usefulness and the limitations of the code and also serve as sample problems. The results of the shock position, overpressure, overdensity, and material velocity for a one kiloton nuclear explosion are compared to the Nuclear Blast Standard (1KT).
