| 摘 要： | 在小尺寸实验箱内综合研究了燃料的质量燃烧速率(?)随通风因子A H~(1/2)和通风口位置高度h的变化。发现因h的不同可改变烟气层对火焰的作用,并引起箱内外气体交换速率和散热状况变化,从而出现不同的燃烧现象。对(?)极大值的变化特点作了讨论。

| Abstract: | The influence of both A H~(1/2), the ventilation parameter, and h, the vent location height, on the mass burning rate of liquid fuel is investigated in a reduced enclosure. It is found that the later has serious influence to the enclosure fire development too. It can affect the action of the smoke layer on flame, and lead the air supply and heat loss condition to change, so some various combustion phenomena appeares. The variation of the maximum burning rate with A H~(1/2) and h are discussed. |
