摘要:应用以计算流体动力学(CFD)为依据的毒性重气扩散模型,以氯气为例,结合具体释放场景,计算得到氯气瞬时泄漏后在不同风速情况下扩散过程的运动特征与浓度时空分布信息;进而根据英国卫生安全执行局毒负荷模型计算得到毒负荷云图;以浓度和毒负荷场分布及变化特征为依据,对伤害等级区域进行划分,对风险进行了动态分析。研究结果表明利用该扩散模型计算的数据能定性和定量地动态分析毒性重气扩散过程的近场风险。
The hazardous gas dispersion model based on the computational fluid dynamics (CFD) was applied to simulate the hazardous gas cloud movement character and gas concentration distribution in time and space. Scene of thorny island tests trail 008 was taken as the release scene and chlorine as release gas. Furthermore toxic load(TL) distribution was computed according to the TL model by Health and Safety Executive Agency (HSE). The results show qualitative and quantitative risk analysis of near field of hazardous gas can be preceded with the data by the model.
