Liquid pool fires in a well-confined ship cabin are experimentally studied. The experimental results showed that the fuel consumption ratio remains stable in the oxygen-lean mode in the well-confined environment for both the tested fuels (i.e., n-heptane and diesel) in this study. The n-heptane pool fire exhibited five burning stages (i.e., initial growth, stabilized burning, transition, boiling, and decaying), while the diesel only showed three stages (i.e., initial growth, stabilized burning, and decaying). Boiling combustion behaviors were not observed when the pool diameter is bigger than 30 cm, but an unusual phenomenon of ghost fire appeared in the later burning stage. Under the oxygen-lean mode, the fuel consumption ratio of n-heptane is 0.19–0.26; and it is about 0.28 for diesel. In the well-confined space, the average mass loss rate per unit area did not change too much under various pool sizes. The average mass loss rate of the n-heptane was observed greater than that of diesel. Besides this, a theoretical model was developed to predict the mass loss rate of liquid fires in a well-confined space, where the predictions agree reasonably well with the experimental data, showing an average discrepancy of less than 10%.

实验研究了密闭船舱中的液池火灾。实验结果表明，燃料消耗率保持稳定在两个测试燃料（的约束良好的环境中的氧-贫模式即在本研究中，正庚烷和柴油）。正庚烷池火表现出五个燃烧阶段（即初始生长，稳定燃烧，过渡，沸腾和腐烂），而柴油仅表现出三个阶段（即，初始生长，稳定的燃烧和腐烂）。当池直径大于30 cm时，未观察到沸腾燃烧行为，但在后期燃烧阶段出现了异常的鬼火现象。在贫氧模式下，正庚烷的燃油消耗比为0.19–0.26；柴油约为0.28。在密闭的空间中，在各种水池尺寸下，每单位面积的平均质量损失率变化不大。观察到正庚烷的平均质量损失率大于柴油。除此之外，还建立了一个理论模型来预测密闭空间内液体火灾的质量损失率，该预测与实验数据相当吻合，平均差异小于10％。
