In this research, a 3D tank farm model of a petrochemical plant was built in order to analyze an LPG tank explosion accident. Furthermore, the Computational Fluid Dynamic (CFD) algorithm was also applied to reconstruct the scenario of the accident. With its 3D dynamic abilities, the CFD simulation results can be used to facilitate the understanding of the spatial and transient distribution of different hazardous physical variables, which cannot be observed from the traditional methods.

After the maximum physical variables of overpressure, pressure-impulse, and thermal radiation temperature were calculated, the results were adopted to estimate the corresponding 3D individual risk value. With the aid of the CFD simulation and the analysis method of maximum physical variable, the researchers can use the simulation results to scrutinize the possible causes and consequences of a chemical accident.

在这项研究中，为分析液化石油气储罐爆炸事故，建立了一个石化厂的3D储罐场模型。此外，还应用了计算流体动力学（CFD）算法来重建事故场景。凭借其3D动态能力，CFD仿真结果可用于促进对不同危险物理变量的空间和瞬态分布的理解，而传统方法无法观察到这些变化。

计算出超压，压力脉冲和热辐射温度的最大物理变量后，将结果用于估计相应的3D个人风险值。借助CFD模拟和最大物理变量的分析方法，研究人员可以使用模拟结果来仔细检查化学事故的可能原因和后果。
