초록

Fire prediction, response and assessment for outdoor storage tanks are essential to disaster management because they have significant human, social and environmental impacts. Therefore, in this study, the fire situation an outdoor storage tank was simulated and the effects of fire on the radiant heat flux were analyzed concerning tank height and fire occurrence time. tank height and fire occurrence time. For this purpose, fire scenarios and specifications of the outdoor storage tank were set, and a study was carried out considered height, fire occurrence time and the operating or non-operating of a water spray system in outdoor storage tanks containing large amounts of Pentane using FDS (Fire Dynamics Simulator). As a results, the radiant heat flux was reduced by more than 50% depending on whether the water spray system was m operating or not. When the water spray system was in operation, the maximum radiant heat flux was 13.75 kW/m2 at a tank height of 14 m, and when the water spray system was not 117 operation, the maximum radiant heat flux was 25.14 kW/m2 at the same tank height. Additionally, it was found that when the water spray system was in operation, the radiant heat flux was 50% lower than when the water spray system was not in operation.
