易燃易爆危险物质泄漏扩散仿真及其应用的研究

Study on Simulation and Application of the Release and Dispersion of Flammable and Explosive Materials

以某轻烃厂泄漏事故为研究对象，研制并开发了一个事故后果仿真软件（ＰＣＩＭＳ）．针对仿真过程中存在的问题，如模型的复杂性、参数的不确定性等提出了处理方法．通过具体生产装置的泄漏扩散后果分析。

With respect to the release accidents of light hydrocarbon plants, a simulation software package named PCIMS for consequence analysis of major accidents has been developed. Some countermeasures have been presented to deal with the problems existing in the process of simulation. Finally, some examples of simulation with PCIMS have been demonstrated.
