Evaluation of the Uncertainty of Geometry Shape on Fire Modeling Analysis Caused by Ignition Area Change of Combustibles
Year: 2024
Type: article
Abstract: In this study, an impact assessment of the uncertainty caused by the geometric shape of fuel in fire modeling analysis was conducted, considering various factors. To evaluate the impact, the geometric shape of the fuel was divided into the area of the ignition source and the flame propagation area of the secondary combustible material. The impact on the target cable tray was assessed by selecting a virtual nuclear power plant compartment as the cause of the fire in the simulation. The results indicated that the smaller the area of the ignition source, the greater the damage to the target. In addition, the flame propagation method of the secondary soft materials showed different trends, even in the same ignition area. Therefore, this tendency should be considered in fire modeling analysis.
