“…Owing to the surrounding obstructions' blocking impact, explosion shock waves in the process of propagation will encounter obstacles after reflection, bypass, and other effects. Instead of being a regular circle, the visualization hazard range radius is more akin to a form of the circular area, which is more in accordance with the actual harm radius in complicated situations (Kang, 2023).…”

In recent years, accidents on buried gas pipelines have happened often in China's cities, mostly when moving natural gas. Natural gas is primarily transported by buried gas pipeline networks, and natural gas pipeline leakage has explosive and flammable properties. It can cause environmental pollution and resource loss, and even cause serious harm to people's lives and a lot of property damage. This paper presents a method for visualizing the consequences of buried gas pipeline accidents based on FLACS software and applies the method to the "7.4" gas pipeline leakage and explosion accident in Songyuan, Jilin. The accident was studied by numerical simulation and visualization of its consequences. The method combines numerical simulation data with mapping software to more precisely recreate the explosion's danger zone and use visualization to analyze the consequences of the gas pipeline network accident. Therefore, the method has some theoretical and practical significance for the risk prevention and accident consequences of urban buried gas pipelines.

In the chemical industry, when a fire occurs, a significant amount of energy is generated due to combustion, impacting other facilities within the plant and potentially leading to severe consequences through a domino effect. For decades, thermal radiation caused by flames has been calculated and predicted through simplified fire modeling. However, with advancements in computing technology, numerical model‐based calculations have greatly improved, allowing for a more realistic implementation that considers actual phenomena. In this study, accident data and 3D modeling information were utilized to conduct fire modeling and simulation based on actual incidents in chemical plants. Through the analysis of simulation results, the initial emergency evacuation distance was provided to minimize the damage caused by thermal radiation, and the final evacuation distance was presented using the probit function. In addition, the study evaluated the impact of generated thermal radiation and overpressure on structures and equipment, providing evidence regarding the potential for secondary incidents. Moreover, the research revealed that the impact of thermal radiation and overpressure decreases due to obstacles, offering insights into the selection of emergency evacuation routes. This study can contribute to supporting effective emergency evacuation strategies in chemical facilities.
