Numerical Simulation for Inert Gas Stimulated by Explosion of Solid Propellant Emitting Visible Light

Abstract:

In this paper, dynamic responses on radiation energy intensity of inert gas are simulated in use of software ANSYS / LS-DYNA when inert gas is stimulated by explosion of solid propellants to emit visible light. The effects for the visible light energy intensity emitted by inert gas are analyzed on different initial pressures in the inert gas container and with different igniting methods by propellants. Simulation results show that, the bigger initial pressure in the container is, the higher the peak value of visible light energy density intensity is and the better the effect of the visible light emitted by inert gas is. There are fewer effects on the peak value of visible light energy intensity emitted by inert gas with different igniting methods. However, it has an impact on the stability when inert gas emitting visible light. The stability is the best when central point of the propellant column is ignited.
