风速对航空煤油池火热释放速率的影响

摘要

利用全尺寸多功能热释放速率综合实验平台,增加环境风速调节与控制模块,在不同环境风速的条件下进行航空煤油的油池火燃烧特性实验研究,实验所用圆形油盘的直径分别为0.2、0.34、0.5m,风速为0～3.78 m/s.实验结果表明:热释放速率与风速影响因子之间存在较明显的函数关系.提出圆盘油池火燃烧热释放速率的表面风速影响因子,并给出了二者的函数关系.%Using full-size, multi function integrated experimental platform for heal release rate, adding the module of ambient wind speed adjustment and control,under different environmental conditions of wind speed, the combustion characteristics of pool fire of aviation kerosene was studied experimentally under different wind speeds. The diameters of oil pan were 0. 2,0. 34, 0. 5 m separately, the range of wind speed was 0~~3. 78 ms '. The results show that there is an obvious functional relationship between the heat release rate and wind speed impact factor, surface wind speed impact factor of the heat release rale of pool fire is proposed, and the functional relationship is given.
