摘要：

In order to study the characteristics of heat flow and temperature in the combustion process of aviation kerosene tank fire, an oil combustion simulation bench was set up. By analyzing the experimental images and data, it is found that the radiant heat flux of kerosene pool fire decreases gradually with the increase of radial distance and height, in which the radiant heat flux is more sensitive to the increase of height and decreases more rapidly with the increase of height. The heat radiation reached the maximum intensity before the heat convection, and then there was a jump in the heat convection intensity in the later stage of the stable combustion, and the intensity exceeded the heat radiation intensity and became the main heat transfer mode in this stage. On the central line of the kerosene pool fire, the flame in the lower area burns continuously with low oxygen concentration, while the oil fire in the upper area absorbs air and has high oxygen concentration, which is the main reason for the difference in the time when the highest temperature at different heights arrives. For different sizes of oil pool fires, the peak heat flux increases with the size of the oil pool, and the peak heat flux of the square oil pool is significantly higher than that of the round oil pool. © All Right Reserved.
