Summary: A full-scale liquefied petroleum gas (LPG) tank model was established using computational fluid dynamics (CFD) to investigate gas dispersion behavior and explosion hazards in process industries. The results showed that heavy gas expansion mainly occurred along gaps between structural congestions and continuous congestion enhanced gas expansion and concentration accumulation. Ignition of a nonuniform concentration LPG cloud resulted in more serious consequences. LPG leakage exceeding 300 s and aperture greater than 10 mm significantly increased the hazard zone. The research provided theoretical references for emergency disposal, disaster assessment, and reserve safety design of LPG leakage and explosion accidents.

Summary: Large-scale Energy Storage Systems (ESS) based on lithium-ion batteries (LIBs) are rapidly expanding worldwide, but the simulation and assessment of battery vented gas explosions in ESS containers are still lacking. This study developed a three-dimensional combustion model to evaluate the hazards of gas explosions to the ESS container structure and surroundings. The results show that altering the vent door pressure without the top vent panel can lead to serious explosion accidents, and lower vented gas concentrations and the introduction of the vent panel design can reduce these hazards.

Summary: Fire accidents in chemical installations can lead to domino effects in atmospheric tank farms storing or processing hazardous substances. Pool fires are a major cause of these accidents, and the primary hazard in domino accidents is the thermal radiation from pool fires. Previous research has focused on the escalation of domino accidents caused by a single pool fire, but this study investigates the failure of a storage tank under the coupling effect of multiple pool fires in terms of spatial and temporal synergistic processes. The study analyzes the scenario of two-pool fires, which accounted for 30.6% of pool fires according to historical accident statistics. The thermal response and damage of a target tank heated by pool fires were investigated numerically. The results showed that the temperature rise rate of the target tanks under multiple pool fires was higher, and the failure time of the tank under the coupling effect of multiple fires was lower compared to the superposition of multiple fires without the first stage. A model for the failure time of the tank under the coupling effect of pool fires was established and verified, showing better deviation than Cozzani's model.

Summary: This study predicts the fatigue life of blasting discs using a combined simulation method and measures the deformation of conventional slotted blasting discs subjected to repeated loading using a high-precision laser scanning method. A relationship model is established between deformation, loading pressure, cycle number, and change in blasting pressure. The results show that the deformation varies linearly with the cycle number and follows a power function relationship with the change in blasting pressure. The deformation can be used to accurately predict the fatigue life of blasting discs.
