RDX激光点火的一维气相模型
One-Dimensional Gas-Phase Reaction Model of Laser-Induced Ignition of RDX
摘要
Abstract
Based on the work of Liau et al. ,a one-dimensional gas-phase reaction model of laser-induced ignition of RDX was established by considering the variations of physical parameters with temperature and component concentration. Using this gas-phase reaction model and finite difference method, the ignition characteristics of RDX ignited by laser radiation of 400 W/cm2 power density at 0. 1 MPa and 300 K were investigated. The calculated results showed that about 90％ RDX transform to gas phase by evaporation and the remaining 10％ decompose in condensed phase. With the accumulation of reactant and increase of temperature, the reaction rate increases gradually and finally the gas phase is ignited at about 10 ms,which is consistent with the results reported in previous literatures.关键词
