The Basic Theory Of Inert Gas Emitting Light Caused By Explosive Shock Wave

Based on the air blast theory, the explosive detonation is simulated in use of ANS YS/LS-DYNA to prove the effectiveness of finite element model. Furthermore, declared the basic theory of inert gas emitting light caused by explosion, the whole process is simulated by adopting ALE algorithm and Fluid-structure interaction method. Then analyzed different influence to inert gas emitting light generated by several factors, such as:species and radius of explosive, species of inert gas and detonation method.The results demonstrate that RDX has a better luminous effect of inert gas produced by explosive than TNT because of its higher detonation velocity. Under consent container volume, there exists optimal radium of explosive to make light-emitting effect the best. Tested the different kinds of inert gas under the stable initial condition, Helium and Neon has the best light-emitting performance. Different detonation has little influence to inert gas emitting light effect, but the stability of center point is better than the others.
