摘要:

为更好地开展航空煤油火灾的消防救援工作,研究环境风作用下上风区航空煤油池火的热辐射分布,探讨航空煤油燃烧速率随风速和油池直径的变化关系;分析上风区热辐射通量随风速和距离的变化趋势;判定不同风速和水平距离下上风区热辐射安全范围。结果表明:上风区热辐射通量随风速先减小后增加,增加的幅度随水平距离逐渐降低;在距油池中心大于3倍油池直径的远场辐射中,上风区热辐射通量随高度先增加后减小,并在距油池液面1倍油池直径的高度处出现最大值。

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.
