摘要
在研究潜艇AIP舱段的氧气泄漏扩散模型基础上 ,研制了封闭空间中的易燃、易爆气体的泄漏扩散三维仿真软件 (SD LO系统 )。SDLO综合利用了有限元前处理软件的网格剖分功能和MATLAB软件的二维及三维图形显示功能 ,模拟了AIP舱室内的氧气泄漏扩散过程。最后给出了氧气泄漏扩散的效果图以及浓度变化曲线图。该文研究对潜艇安全监控预警系统的建立有一定的参考价值和指导意义。
On the base of study on the discharging dispersion model of Oxygen in the cabin of AIP submarine, a three-dimensional simulating software named SDLO for release and diffusion of inflammable and detonable gas in sealed space has been developed. SDLO takes full advantage of the meshing outcomes of finite element pre-processing software and the 2-D and 3-D visualization technology by MATLAB. The discharging diffusion process of oxygen in AIP is also simulated. Finally, the diffusion result and concentration curves are provided. The study is useful to establish the safety monitor-control and early-warning system in AIP submarine.
