泄漏气体扩散模型的研究与应用

摘要

通过对泄漏源模式及泄漏影响因素的分析，以湍流扩散微分方程为基础，对泄漏气体扩散行为模型化，得到有界和无界的烟团和烟羽模型，并进行了实例分析。扩散模式的研究可以确定事故影响范围、危害程度，为事故应急救援，人员撤离等提供参考。%Through analyzing the mode of leakage source and factors to influence the leakage,the diffusion model of leakage gas was established based on turbulent diffusion differential equations, bounded and unbounded puff and plume models were obtained, and a example analysis was carried out. The study of the diffusion model can be used to determine the influence scope and damage degree of the accident, which can provide a reference for emergency rescue and evacuation.
