Abstract

Abstract:

In order to better carry out the fire rescue work of aviation kerosene fire， the thermal radiation distribution of aviation kerosene pool fire in the upwind area under the action of the environmental wind was studied， and the relationship between aviation kerosene combustion rate and wind speed and oil pool diameter was discussed. Variation trend of heat radiation flux in upwind area with the wind speed and distance was analyzed. Safety range of thermal radiation in the upwind area under different wind speed and horizontal distance was determined. The results show that the thermal radiation flux in the upwind area decreases first and then increases slightly with the wind speed， and the increasing amplitude decreases gradually with the horizontal distance. In the far-field radiation whose distance to the center of the oil pool greater than three times of the oil pool's diameter， the thermal radiation flux in the upwind area first increases and then decreases with the height， and the maximum value appears when the height from the surface of oil pool is the same as the diameter of it.
