    Abstract
  • In order to study the influence of flame characteristics on cook-off bomb in pool fire under the condition of fast cook-off, a fast cook-off model of pool fire was established, and the heat transfer characteristics of the cook-off bomb were obtained, then the influences of the placement height of the cook-off bomb and the size of the oil pool on the flame characteristics during the burning process were analyzed. The results show that with the increasing placement height of the bomb, the highest temperature region of the bomb surface shifts from the upper surface to the lower surface, and the peak radiation heat flux shifts from the top to the bottom of the bomb. With the increasing size of the oil pool, the surface temperature of the bomb becomes more uniform, the heat flux absorbed by the bomb increases, and the surface temperature of the bomb increases. Therefore, in the fast cook-off test, both the placement height of the bomb and the size of the oil pool affect the flame characteristics, and then the fast cook-off characteristics of the bomb.
