摘要

在石油、化工等行业中经常使用具有毒害性与较高泄漏频率的危险性气体，存在严重的泄漏事故后果。为了获得气体泄漏后扩散过程中关键的浓度时空分布信息，建立了危险性气体释放后的运动特征及浓度场时空分布的计算流体力学（CFD）模型，并利用FLUENT代码对Thorney Islands Trails实例场景进行了模型验证计算。结果表明CFD模型计算结果能很好的获得气云的运动特征和气体浓度时空分布信息。

Abstract

Accidental release of the hazardous gases with high release frequency

widely used in petroleum refining and chemical industries will cause serious effect.In order to obtain the key information to manage the hazardous gases release accident

a computational fluid dynamics (CFD) model was established to simulate the movement characteristics of released gas and the distribution of hazardous gas concentration in time and space after release.The instantaneous release scenes from Thorney Islands Trails were used to validate the CFD model with the software Fluent.The result showed that the model could provide the information of the movement characteristics of the gas cloud and the distribution of hazardous gas concentration in time and space.
