一维冲击波和爆轰波计算程序SSS

本文叙述一维程序SSS的理论和结构。介质采用流体弹塑性模型。爆轰反应有四种可选方式:Arrhenius律、C-J比容法、方波法和Forest Fire方程。爆轰产物可选用HOM或JWL状态方程。SSS程序的特殊功能有,激光效应、爆轰增长、强爆炸波、散心爆轰和瞬时爆轰等,初始起爆或能量释放位置可任意设定。本程序部分参考了美国洛斯阿拉莫斯实验室的一维程序SIN。本文列举的算例把这两个程序作了比较。

SSS:A CODE FOR COMPUTING ONE DIMENSIONAL SHOCK AND DETONATION WAVE PROPAGATION

The one-dimensional hydrodynamic code SSS for shock and detonation wave propagation in inert and reactive media is described in this paper. The elastic-plastie-hydrodynamic model and four burn techniques, the Arrhenins law,C-J volume, sharp shock and Forest Fire are used. There are two options of the equatin of sta te for detonation products:HOM and JWL. Compared with it's reference-the SIN code published by LANL, the SSS code has several new options:laser effects, blast waves, diverging and instantantaneous detonation waves with arbitrary initiatron positions. Two examples are given to compare the SSS and SIN calculations with the experimental data.
