Pantousa developed a numerical simulation model to investigate the thermal buckling characteristics of empty thin-walled steel tanks under multiple pool-fires. The solid flame model (empirical) was adopted to model the fires, and the nonlinear finite element code MSC-Marc software was used to establish the numerical simulation model. On this basis, Chen et al. adopted the Fire Dynamics Simulator (FDS) to explore the coupling effects in double-fires scenarios, in which the enhancement of thermal radiation intensity and flame height by carbon black was considered. The ANSYS Workbench was adopted to analyze the thermal response behavior of 5000m 3 diesel dome tank under the coupling effects of double-fires. Subsequently, an improved CFD-based method was proposed to model the consequence of multiple pool fires.
